[References](#references) 17 | 18 | ## Introduction 19 | The idea of this project is to build a model for e-commerce data that summarize large amount of customer reviews of a 20 | product to give an overview about the product. The result of this model can be used to get an overview of what are the 21 | most important reviews that many customers complaining or praising about a particular product without reading all of 22 | the reviews. The main tasks involved in this project are data collection, data cleaning, implementation of two 23 | summarization algorithms and getting the final summary in Apache Spark. 24 | 25 | 26 | ## Dataset 27 | ### Data Collection 28 | The dataset used for this project is crawled from Amazon.com. The dataset contains products' reviews in separate files 29 | for each product, each file contains maximum of 1000 reviews. Since the reviews are sorted by ranking, the first thousand 30 | reviews are more than sufficient for the summarization task. Each review in a file contains `review_id`, `ratings`, 31 | `review_title`, `helpful_votes`, `total_votes` and `full_review`. The reviews file for a product is named by its 32 | `product_id` and all the metadata about the products are stored in a file called `iteminfo.txt`. 33 | 34 | **Note:** Data is collected using the [customer-review-crawler](https://github.com/iamprem/customer-review-crawler) which is 35 | **forked from [maifeng's crawler](https://github.com/maifeng/customer-review-crawler)** written in java. The original 36 | version was outdated, so i had to rewrite the whole code that are used for data collection for this project. Please see 37 | the [commit history](https://github.com/iamprem/customer-review-crawler/commits/cloud) for the changes that I made to the forked version. 38 | 39 | ![Commit log comparison between maifen and myself(iamprem)](https://raw.githubusercontent.com/iamprem/temp/master/assets/commit_tree.png) 40 | #### Description of dataset 41 | 42 | **product_id.txt** -- a file that contains reviews about a product. 43 | 44 | review_id - Unique id given to a review 45 | ratings - Integer value ranges from 1 to 5, describes rating of the product 46 | review_title - Punch line given by the reviewer for their review 47 | helpful_votes - Number of people found the review was helpful(upvoted) 48 | total_votes - Number of people upvoted or downvoted the review 49 | full_reveiw - Full review given by the reviewer 50 | 51 | **itemsinfo.txt** -- a file that contains all the product metadata 52 | 53 | product_id - Unique id for a product 54 | product_name - Listed name for the product in Amazon.com 55 | price - Price in US Dollars 56 | 57 | #### Challenges in Data Collection 58 | * Main challenge in data collection is denial-of-service from Amazon.com. So no more than one request can be given per 59 | second. This was handled by backing-off for a minute when 503 error occurs and retry after a minute. Though data 60 | collection is time consuming, the summarization task doesn't depend on the number of data samples available. So 61 | product reviews for 25 products are retrieved for this task. 62 | 63 | #### Sample Data 64 | 65 | First five reviews of product "Samsung Galaxy Note Pro 12.2"(B00HWMPSK6) 66 | 67 | R3M37E07KXEPVP 5.0 One hell of a tablet 1190 1214 *** Updated 5/8/2014 - if you're using Dolphin Browser with Adobe Flash player do yourself a favor and do NOT update Dolphin Browser if prompted to in the Google PlayStore. It seems like every time they update Dolphin there's a chance for Flash to no longer work without jumping through more hoops *** I come from a Windows OS background and I'm an ex-Apple iPhone (now Galaxy Note 2) and iPad user. I've been waiting a long time for a tablet like this to be released: a large screen, expandable memory and the freedom of Android. Thanks to my Note 2 I have a little over a years of experience with Android OS but I knew what to expect from the Note Pro 12.2. Originally I had my eyes set on the Samsung Galaxy Note 10.1 2014 Edition (32GB, Black), after months of waiting and playing I decided to bite the bullet and buy it. Just before doing so I read of a possible 12" model coming out in the following year so I figured another 6 weeks of waiting can't hurt and patience definitely paid off. Comparing the Note 10.1 2014 Edition and the Note Pro 12.2: One big issue that annoyed me with the Note 10.1 2014 Edition ("14E") was the ridiculous My Magazine app that never goes away. It constantly hogs system resources as it runs in the background even after forcing shut downs of the app, and disabling the Home button link to this app didn't help as it would just keep running in the background. I noticed that the 14E was constantly using 1.5-1.7GB of its 3GB RAM total at all times even after factory resets, disabling apps and reboots. Thankfully the Note Pro 12.2 ("NP12") doesn't have this issue as it hovers around 1.2GB of memory used after a reboot. Even having pages of the magazine feeds and widgets running it still allocates memory usage better and best of all: no pesky My Magazine app! Luckily I was able to compare both tablets side by side at the local Best Buy. This was a large factor in my decision to go with the NP12 over the 14E. Both tablets are about the same when it comes to hardware but there are other major differences between the two. Let's go over some of the features that the NP12 has over the 14E... 1. Over 2 extra inches of real estate on the screen. This means writing on the NP12 with the stylus while in portrait mode is very much like writing on a real piece of 8.5 by 11 inch piece of paper, aka standard notebook paper. The palm rejection does a great job of making sure only the stylus gets recognized for input (if you want that on). I find that a 10 inch screen is too cramped to comfortably write notes on. Do your research, this is a 12 inch tablet so don't be surprised and don't consider it a downside. 2. Larger, longer lasting battery rated at 13 hours (9,500 mAh) versus the 14E's 9 hours (8,220 mAh). My mixed use gets me anywhere from 8 to 12 hours before plugging it in for a charge, depending on what apps I'm using and what the brightness/volume is set at. Lots of gaming/graphic intensive apps will exhaust the battery quickly whereas reading PDFs, E-books, etc. is where the battery really stretches its legs. There are numerous settings and options for the tablet to use minimum energy which I will go over later. 3. Multitasking on the NP12 is fantastic. Multi Window allows you to run 2, 3 or 4 apps on screen at once (the 14E supports up to 2 apps side by side). There are many apps compatible with Multi Window. You can also resize the windows depending on where you need the most room on the screen. Chatting with friends on Hangouts, surfing on Dolphin Browser, watching your favorite movie and checking/writing Emails all on the same screen is productivity at it's finest. You can save Multi Window templates too for quick access so that you don't need to drag the apps one by one every time you want to multitask. Just select your template and all the apps open up automatically. I usually have 3 apps going at once: Video (or Music) at the top left, AquaMail at the bottom left and Dolphin Browser taking up the entire right side of the screen. Bonus feature: there is a trick that allows more than 4 apps open at once on the NP12, up to 9 apps total. First use Multi Window to load up whatever 4 apps you want on the screen, then hold the S-pen above the screen and press the pen's button which bring up Air View. On the Air View pop-up select Pen Window. Now use the S-pen to draw a box and then choose an app to launch in that box. The app loads up in the box you drew. It comes up as a floating window that can be resized, moved around on the screen and also minimized to a floating "bubble" that you can move around anywhere you want. You can do this 5 times total. So 4 apps via Multi Window and 5 apps via pen window. The Multi Window apps are all joined on the main screen while the 5 pen window apps are solo floating windows and can be minimized to a bubble to have them out of the way. Pretty cool! 4. KitKat 4.4: the new "Magazine Home" user interface (UI) is a little like Windows 8 but at the same time its different. After playing with it for a little while you'll actually want to use it and set up multiple pages filled with your news subscriptions, feeds, widgets, etc. I did not think I would like the dashboard/widget style UI but on a screen this size it works well and looks great. Basically you can set up different pages filled with all sorts of widgets ranging from: Application widgets (Email, Calendar, Music, Video etc.) Social widgets (Twitter, Flickr, YouTube etc.) News widgets (Art & Culture, Science & Technology, News, Style, Sports, Business, etc.) Each news category has dozens and dozens of publications to subscribe to and I find myself spending more time reading articles than I ever thought I would. If you're not a fan of the new UI the familiar Android desktop is still there with your standard icons and widgets. If you'd rather customize the tablet completely I highly recommend Nova Launcher. Those are the main differences to me. Now onto some general information about the tablet as well as apps I use and features worth checking out: Like every other phone, tablet and computer out there the NP12 does come with some bloatware. There are different types of bloatware so I'll cover each one: 1. Some preloaded apps can be uninstalled completely giving you back some minor storage space. This is a good thing. 2. Some preloaded apps cannot be uninstalled and instead can have "most" of their data cleared and then "turned off" - these apps remain installed on the tablet but are disabled. Some of the preloaded apps that can only be "turned off" are Chrome, e-Meeting, DropBox, Gmail, Google+, Twitter, Cisco WebEx and others. These are just some that I do not use myself so I turned them off. Even when turned off/disabled, these apps still take up some room but its very little, 5MB or less per app. 3. Some apps cannot be uninstalled nor can they be turned off. They can have most of their data cleared though. Either way this is just plain stupid. I can only think of two off the top of my head: Evernote and RemotePC. I don't use these particular apps at all so why can't I at least disable them so they don't show up in my apps list? Both of these apps use about 9MB of space combined. Again it's not a deal breaker for me but Samsung y u do dis?! I bought the 32GB model. The tablet needs about 6-6.5GB for the operating system and preloaded software/apps. Out of the box you have around 25.5GB of space to play with, this of course depends on what preloaded apps you choose to keep/update or disable/uninstall so your free space will vary. A great investment would be a SanDisk Ultra 64 GB microSDXC Class 10 UHS-1 Memory Card 30MB/s with Adapter SDSDQUA-064G-U46A, which gives you another 60GB~ of extra space for apps, movies, music, pictures, whatever you want to put on it. This SD card plus the tablet's free space adds up around 85GB which for me was more than enough. It's very easy adding your media files to the SD card, just plug the card into your PC with the supplied adapter and create folders like Music, Movies, etc. then copy/paste or drag and drop Artists folders into the Music folder, and videos into the Movies folder. I loaded music, movies and pictures on the SD card and I leave the tablet's internal storage for apps since applications seem to run faster off of the internal storage as opposed to off the SD card. If you think you need more space you can go big with SanDisk's newest 128GB card also found on Amazon. The screen is beautiful. High quality photographs and wallpapers at the native resolution (2560x1600 or bigger) look really, really good. If you're looking for some stunning wallpaper for your tablet check out: interfacelift.com/wallpaper/downloads/date/widescreen_16:10/2560x1600/ This model is WiFi ONLY! There is NO slot for a SIM card. The WiFi model also works with your MiFi device and can also connect to the internet via a mobile hotspot such as your iPhone or Galaxy smartphones. I use my Note 2 smartphone as a mobile hotspot and it works great. If you are looking for the 4G/LTE version you'll need to check out the model that Verizon offers. It's available through Verizon or here on Amazon, just search "note pro 12.2 verizon" GPS - yes the tablet has GPS built in, you do not need to be connected to the internet for GPS to work (such as the Google Maps app). Hancom Office is included with the NP12. This is Microsoft Office for Android, simple as that. You get full versions of word processing (Word), spreadsheets (Excel), and slideshow (PowerPoint). It all works very well with the large 12.2" screen and I find it very familiar after using MS Office for so long. You can even open existing word, excel and powerpoint documents with Hancom Office and continue editing and creating. Hancom Office is fantastic, however I must admit it was a little involved to get it up and running, so I will explain as best I can: After the initial setup of your NP12, go to your apps (bottom right, little white squares) and launch the "Samsung Apps" app, it will require an update so go ahead and download then install the update. After that is done, go back to your apps and launch Hancom Viewer (there is also a Hancom widget in one of the two default Magazine Home screens if you want to launch it that way). When you launch it a small white box should come up and it will say installing fonts and files, etc. so let it do that and when its done the Hancom Viewer app should open completely. On the left side select Office Download, then OK. This should open the Hancom Office Update Manager. When you do this there's a good chance the Update Manager will prompt you to update it so go ahead and do that. After its updated you can launch it again, the Hancom Office Update Manager is where all the Hancom apps are downloaded/updated/installed. You'll see 12 rows of Hancom apps such as Hcell, Hshow, Hwp, etc. Update and/or install all the ones that need to be done by pressing the rectangular button at the far right of each row. Each time you press the install or update button on the far right it will take you to Samsung Apps where you can press the Update button. Go ahead and update all 12 apps if needed, some may already be updated but will need to be installed (or vice versa). Once every button on all 12 rows is greyed out in Hancom Office Update Manager, then you know you're done! Now just go to your apps and launch whichever one you like. Hcell is excel, Hshow is powerpoint, and Hword is word processor. Hangouts is a cool app and it comes with the tablet. It lets you text/message anyone with an email address or phone number. If you are familiar with iMessage then you know what this is. *** UPDATED BELOW Dolphin Browser is a must for surfing the web. It is fast, supports tabs, and has a cool feature named speed dial. A speed dial is a bookmark placed on the Dolphin home screen for easy, one-tap access to the webpage. You can have pages of speed dials, its very useful and beats going down a list of bookmarks looking for a particular site. Perhaps the best feature of Dolphin Browser is that it supports Adobe Flash and Java. I bet your iPad can't do that! What is Adobe Flash? Many of the websites you visit require flash to display the content properly, some websites even have flash animation and to play those you will need the flash player. One example of flash required content is Youtube videos, and Youtube videos that are embedded in other websites. Here is how to enable Flash on the NP12: cultofandroid.com/49840/install-flash-player-android-4-4-kitkat/ *** NOTE: the link to download the Flash Player Installer on the website above is broken. Here is an updated working link for the Flash Player installer: downloadandroidfiles.org/Files/Apps%20%28APK%29/KitKat.Adobe.Flash.Player.11.1.apk When you're all done installing Flash player you should head over to the official Adobe Flash website to test the flash player so that you know it works. On the website you should see a bouncing red box. If not just refresh the page and you should see it the second time around. The Adobe page to test your flash player is: adobe.com/software/flash/about/ PROTIP: ONCE YOU GET DOLPHIN BROWSER AND FLASH PLAYER UP AND RUNNING, DO NOT UPDATE DOLPHIN BROWSER IN THE PLAYSTORE UNLESS ABSOLUTELY NECESSARY. It's not worth taking the chance of the update messing up Flash Player. Amazon Instant Videos - yes, you can watch them on this tablet. Yes, you'll need Dolphin Browser and Adobe Flash installed and correctly configured. If you followed the aforementioned links you should be all set by now. Here is another link specifically dealing with streaming Amazon Instant Videos on KitKat 4.4, which is the tablet's operating system. This worked for me and it should work for you!: the-digital-reader.com/nates-reviews/stream-amazon-instant-videos-android-tablet/ *** UPDATED ABOVE Splashtop 2 Remote Desktop is a remote desktop app that you can download for free and in my opinion works better than the RemotePC app that comes preloaded on the tablet. This app allows you to access your PC or Mac's desktop environment so that you basically have your entire PC/Mac on your tablet. It takes advantage of the 12.2" screen by filling it entirely with your computer's desktop. This is useful since you can run all your PC/Mac programs right on your tablet. It works really well and is probably my favorite app that I have come across. There is an optional paid upgrade to the app that let's you remote into your PC/Mac from anywhere. For now I am just using the free version to access my Windows PC, very cool and worth the download. If you want to connect this tablet to your HDTV, a projector or anything with an HDMI input, you'll need a Samsung MHL HDMI adapter. This adapter allows you to mirror your tablet's screen onto your HDTV or other source. I also noticed that you can play a movie on the tablet (which also displays on your TV) and still use the tablet for other apps while the movie plays uninterrupted in the background of the tablet but still in full view on the TV. In other words you can play your movies or shows on the big screen while surfing the net or whatever apps you want to use on the tablet. This adapter is available here on Amazon but I chose to buy mine off of ebay. If the one sold on Amazon does not say "shipped and sold by Amazon" there is a good chance you will get a cheap knockoff adapter that will not work, just read the reviews from other buyers for yourself. If you want to try your luck the adapter can be found here: Samsung ET-H10FAUWESTA Micro USB to HDMI 1080P HDTV Adapter Cable for Samsung Galaxy S3/S4 and Note 2 - Retail Packaging - White. The seller I found on ebay is selling the legitimate Samsung adapters that have the hologram sticker and QR Code on the box indicating that it is a genuine Samsung product. Mine arrived promptly and works great. Save yourself the headache and get a genuine one here: ebay.com/itm/350958988570 Bluetooth is available so you can connect a BT mouse and keyboard if you like. Samsung makes an S Action mouse especially for the Note Pro and Tab Pro line of tablets and it works very well. The mouse buttons are specifically linked to actions such as Recent apps, Multi Window, Back, Menu, etc. I got to play with this mouse recently and it's fun although I opted not to buy it as I don't see me using the mouse enough. If you are interested its available at Best Buy (search ET-MP900DBEGUJ) and here on amazon: Samsung S Mouse for Tablets (ET-MP900DBEGUJ) You can also connect USB peripherals to the tablet using a USB OTG cable like this: Black Color Micro USB 3.0 9pin OTG Host Flash Disk Cable for Samsung Galaxy Note3 N900 N9000 10cm. This allows you to connect a number of USB devices such as a mouse, keyboard, flash drive, external hard drive, even a PlayStation 3 controller to the tablet with the ability to access them - If you have a lot of movies on your external hard drive you can use the OTG cable to connect it to the tablet to watch movies. Another example is if you have a thumb drive on your keys, you can connect it to the tablet to access all your files. You can connect more than one USB device at a time by using a USB hub along with the OTG cable mentioned before. I don't recommend connecting more than two devices at the same time in the USB hub, especially if its a device that sucks up a lot of power like an external hard drive. Netflix, Vudu, Amazon Kindle, Google Earth all work great, no issues. If you want to stream video from the tablet to your Smart TV (like Apple AirPlay) check out the AllCast application made for Android devices. Extending battery life is simple: disable the vibration/haptic feedback and keyboard/stylus sounds as it really isn't necessary. Keep the brightness on Auto and the volume at half or less. When you're done using it for a while make sure you close all your apps and clear your RAM before putting it to sleep. This will greatly increase the standby time of the tablet so that when you pick it up again later it will still have lots of juice left in it. This is the procedure I do: Swipe down the top of the screen Clear your notifications by pressing the X under the sound bar Swipe down the top of the screen again Turn OFF WiFi (important) Press the "Recent apps" soft button (to the left of the Home button) Select Close all Press the Recent apps button again (no apps should be running now) Select Task Manager Select RAM manager on the left Press "clear memory" - do this AFTER closing your apps Press Home button Press Recent apps button a third time Select Close all (this closes Task Manager) Press Power button to put it in Sleep/Standby mode Doing the above every time sounds tedious but after a few times its second nature and you will notice the battery percentage stays where you left it (or it only drops only 1 or 2%) even after an entire 24 hours in standby. If you notice when opening/closing apps and switching between apps there is a slight visual delay, this is normal. It is meant to make the transition between apps look "pretty" - Microsoft OS and Apple iOS have something similar. This will eliminate the windows animation and transition effects which in a nutshell will make the tablet run much quicker and smoother: Swipe down and go to Settings Go to the General tab Scroll down to About Device Press the greyed out Build Number section continuously, 5-7 times Developer Options is now enabled right above About Device Under Developer Options, scroll down to the Drawing section Set all three of these settings to OFF: "Window animation scale" "Transition animation scale" "Animator duration scale" You'll notice how snappy it runs after doing that. Another available on/off toggle is the double-press Home button to bring up S-Voice. When you press the Home button twice quickly it will launch S-Voice. If you'd rather have this feature disabled read on: Launch S-Voice by pressing the Home button twice (or via apps > Samsung folder > S-voice) At the top right press the 3 small squares then select Settings On the next window the second row down is the "Open via the Home key" on/off toggle. Some apps that my girlfriend has recommended for drawing/painting/art. She is a graphic designer and bought her own Note Pro 12.2 soon after playing with mine so I will take her word for it. I have seen some of the pieces capable with this tablet and it is impressive. Also note that the files you create and save in some of these apps can be opened and worked on in Adobe Illustrator and Photoshop: Artflow Infinite Painter Sketchbook Pro Sketchbook for Galaxy (included with the tablet) Fresco Paint Pro Paperless Onto the accessories: I am using the Samsung 12.2" Book Cover with my NP12. It is well made, very sleek looking and does protect the back and corners well. The stand works well in both positions. Don't plan on taking too many pictures with this cover though because when opened the cover wraps around the back and blocks the camera lens. That is OK though because you should never be using a tablet to take pictures. Ever. Stop. No.... don't do it. You look ridiculous. I'm pretty sure there is a law against this - ipadisnotacamera.com - I rest my case. Anyway, I bought mine at the local Best Buy and you can find it on bestbuy.com - search for "samsung book cover 12.2" The IVSO Slim Smart Cover Case is nice too and protects the tablet a little better than the Samsung Book Cover but I find the IVSO's stand to be a little more flimsy and I don't like that it makes the tablet sit upside down (home button on top) when using it in your lap. On the plus side the camera lens isn't covered with this cover and there's a thin magnet that holds the cover to the tablet so it doesn't flop around. IVSO Samsung Galaxy Note Pro 12.2/Tab pro 12.2 Ultra Lightweight Slim Smart Cover Case with Auto Sleep/Wake Function-will only fit Samsung Galaxy Note Pro 12.2/Tab pro 12.2 Tablet (Black) I picked up this Galaxy Note Genuine Wacom Touch Pen 8pi Stylus (ET-S200EBEG) - Black. It is about the same thickness as a regular pen so its easier on your hand and it has an eraser on the end, too. Here's a tip: go to settings > controls > S-pen and at the top make sure "Turn off pen detection" is not checked, now you can use a second stylus without needing to remove the factory stylus from the tablet. If you're going to be using the S-pen a lot this is a very good investment. If you're looking for a great sleeve, check out the Merkury Innovations 12-Inch Solid Zipper Sleeve, Black/Blue (M-LL1090). It fits this tablet perfectly, even with the Samsung book cover on it and the quality is top notch. I love the fit and finish of this sleeve and how well it fits this particular tablet, the side pocket for the charge cable/external HDD is a bonus. Need a longer USB 3.0 charge cable? I bought one of these here on Amazon: Cable Matters SuperSpeed USB 3.0 Type A to Micro-B Cable in Blue 10 Feet. It works just as well as the factory cable for charging and is available in 6, 10 and 15 feet - useful if the nearest wall plug is too far away. I like choices so I bought another sleeve, this one has a handle though: Evecase 10.6~12 inch Tablet, Netbooks Ultraportable Neoprene Zipper Carrying Case with Dual Hidden Pocket & Handle - Black/ Red. This sleeve is great because of the handles so I can throw in the tablet and carry it around just like that. If using my backpack I'll use the other sleeve mentioned above inside my bag. This sleeve is just as nice as the other and also has a side pocket. The black/red color looks sharp. Last but not least: the User Manual. This has TONS of useful information about the tablet. Definitely worth it to look through this, in fact most questions that people keep asking about the tablet can be answered just by looking in the manual.

For those that have a Galaxy note phone, the Note Pro tablet is more than just a larger version of the same. The functionality is greater, the multitasking is excellent, and from both a personal and business use, it has met my every expectation. I will address a few areas of concern I had before purchase to try and help anyone that may be feeling the way I was. SIZE - my job has me on the road marketing every day. This tablet, to me, is portable enough to not be a problem or feel like I am lugging around something uncomfortable. I carry a clip board with a few forms and the note pro 12.2 in a slip cover case (until I can get my hands on the book cover case which is back ordered). When I read the initial reviews I was terrified to buy this thing sight unseen as many talked about it being too big or too heavy. It is not too big and the weight feels light next to the surface pro. If you are looking for a large tablet screen...This is for you. Also the large screen allows for the full size keyboard which is nice (this review is being typed on the screen) MAGAZINE UX - the difference in the updated interface had me scared. Is it like the new windows tiles? Is it completely different than what I am used to on the Galaxy Note 3 phone? Here is the deal. The Magazine UX is not bad. I am not a fan of the new Microsoft Windows tiles which i had on the Surface Pro. The UI is different and better in my opinion. You can set up your tablet to look almost identical to your Samsung Note phone if that is what you want. There has to be at least one screen of the magazine but to be honest, I have it set up to where I really like it. When I hit the button to go to the home screen it takes me to the same setup I have on my phone which is folders with different apps, time and weather, etc. 32 or 64 GB - Being an early adpoter, the 64gb model was not available on release. It is unlikely that you will be using this tablet to shoot a ton of HD video (which is the biggest storage hog) and with an addition of a 64GB sd card that you can swap out if needed, 32gb device memory works just fine. WiFi or 4G - that depends on your needs but if you can use your phone as a hotspot, why pay extra for a cell radio in the device plus pay more to add it to a cell plan? The answer for my needs was WiFi works perfect and tethers with my phone on the road. I can't say much about the battery life yet as I have only charged it once. It had about 50% charge when I pulled it out of the box after purchase. CONCLUSION - I was disappointed in the info updates on this device before the US release. All of the videos and reports were all from CES and there were no new hands on reports. I can tell you that this device has a premium price but also carries premium capabilities. If you just want to update a status on Facebook and play candycrush...This isn't for you unless you want to spend the money for the screen size. If you want a nice big screen to multitask and you are either familiar with Android or are willing to educate yourself on the possibilities. You will be impressed. 69 | R17NYA6EFL1HHZ 5.0 Great Tablet! Well worth the price! w/ Bonus Zagg keyboard review! 207 223 April 2014 Update: It has been over a month of usage with the 12.2 and I have to admit my experience has become more and more positive. Things I am liking is the the stellar battery life, the way apps update to work better with 4.4os, the physical durability, the screen sharpness/brightness, and the internet browsing experience. I love the multi-day battery power you get. I realize even with the screen up at 80% brightness watching Netflix all day the battery still takes forever to drain. The only App that seemed to cause Battery drain and slow recharging issue was Word-With-Friends, Blurb Checkout and HP Printer Services. Once you delete those and make use of Task Manager to curb background activity everything improves. Also keeping GPS Antenna off helps. Apps seem to be updating regularly to work smoother on 4.4os and to also support the multi window display. So now more apps can be swiped into new windows when in multi window mode. By contrast I have some popular apps on my iPhone that are only now updating to work better with last year's iOS 7. I'm finding the feel of the tablet is great for daily use. I love the faux leather back and aluminum trim. You don't necessarily need a case like you would on a scratch prone-metallic iPad. The faux leather is soft to the touch and easy to grip, yet handles daily commuting bangs and scrapes well without any signs of wear and tear. One thing I didn't expect though is the faux leather to be a bit of a fingerprint magnet. I tried using other tablets since and I now realize how great the screen is. Apart from the slight fuzziness you get when importing low res pics (or browsing the Facebook/eBay app) hi res images, websites, eBook/Adobe Reader text and colors always look sharp and bright. I even take back what I said about the 10.1 Note Pro's screen being possibly better. The 12.2 has a greater overall screen. As long as you stay away from your Grandma's 1 MP pictures and don't expect extra sharp images on the Facebook and eBay app then this tablet will make you happy. Actually if you use Chrome or Internet to browse Facebook and eBay then the images will look sharper and will scaled up properly. This brings me to my final impressions for the 12.2: the web browsing experience is second to none! I'm very impressed with the consistent speed and page layout of the Chrome and Google web apps. This is the first tablet where I can say anyone's dependence on a full desktop PC or laptop PC for internet service will be greatly diminished. The only thorn in this positive is that Adobe Flash material may or may not load on certain websites but there is an Android Flash Player Patch (not found in the Play Store/Samsung Apps) that you can install thru your web browser to work around this. Positives aside there have been some hiccups with the 12.2. There is a slight interface delay when using the S pen on certain Apps. It works perfectly in S pen native apps. I don't find myself using S pen for what I normally do on my 12.2 so it is no bother to me but still worth mentioning. Also the Android/Samsung Gallery and File Management system can get cluttered if you tend to store a lot of documents and media. Add in the automatic Facebook/Dropbox media file import and you may find yourself lost in a sea of tricky to remove pictures that you never put on the tablet. However, coming from an iOs iPhone background where Apple manipulates your media and files for you I am actually enjoying the freedom of organizing my images and files the way I want. I don't really use the Magazine but, unlike widgets, the Magazine tiles do not auto update. [Yeah I checked with Samsung and] there is 'currently' no method for selecting them to automatically refresh with new stories and content. It has to be manually done for each tile every time you open Magazine. This actually defeats the purpose of what the feature is about-quickly exposing users to new and newsworthy information. On the flip side I'm curious how battery life will fare once Samsung allows background auto update of all those tiles. Over all I think anyone who chose this tablet will be happy. I still don't know why haters still rate the 12.2 low because Samsung wants $750 for a 12.2 tablet when in the same stores Samsung smart phones, iPads and iPhones sell for $799+. --------------------------------------------------------------------------- I originally wanted the Note 2014 10.1 for the holidays but decided to wait when the 12.2 appeared at CES. After seeing a some early online gadget reviews and videos I went into Best Buy held both the 10.1 and 12.2 and in under 3 minutes I was sold on the Pro 12.2. What I realized after looking at the 32GB 10.1 at $549 versus the 32GB 12.2 at $749 that for $200 more you get a lot more than just a bigger screen. After a month of daily use with my 12.2 did I make a good choice? Let's find out. PROS: The battery life is very good. I usually go all day with usage (bluetooth, wifi, apps running, screen brightness at 60%-auto brightness set to OFF) and never go below 70%. Some applications (words with friends) and widgets will drain battery quicker even if you are not directly using them so it is best to use the task and application manager in settings to see what is using your battery the most. Also GPS antenna being on all the time will kill the battery life. The first thing you will notice is that the 12.2 handles multiple tasks VERY quickly. It is not as quick as my iPhone 5S when opening heavy apps quickly like Facebook but because 99% of the time I am doing more than one thing at a time on my 12.2 any lag (minute as it maybe) is completely forgivable. In fact other than Facebook I have not notice anything to be slow on this tablet. YouTube, GPS-Google Earth/Maps, Web Browsing, Hancom Office, etc... can all run at 100% at the same time on the same screen. I had absolutely no issues with stuttering, slowing down or freezing up like some review videos have griped about. The software has updated since I took it out the box so that maybe the trick. Make sure to update your software and all the apps to get the most up to date performance. This tablet also doesn't get hot in my lap at all when doing heavy work. Netflix, YouTube, streaming Video playback is smooth, crystal clear Hi-Def and looks amazing! Images and text on Mazagine, web browsing apps, FlipBoard, emails, Adobe Reader, games, ebooks, etc... all look crisp, bright and vividly sharp. The Chrome and Internet web browsing apps are blazing fast! I never liked web browsing apps on tablets and mobile phones because it was never as quick and natural as internet on a PC or notebook but here it feels natural and fast. Pages are full pages and not scaled down versions of websites. I also found the Android web browsing experience MUCH BETTER than Safari on the iOS iPads. Contrary to some early YouTube reviews I did NOT find this tablet to be too big or heavy for one handed use. The average adult should be able to hold and use it in one hand while standing. The Note Pro 12.2 is the around the same weight as my fiancé's pre-iPadAir iPad3. At 8"+ by 11"+ inches the 12.2 Note Pro shares the same footprint as a standard sheet of paper (Go to your printer or office desk and pick up a standard sheet of paper it is the same size as this 12.2 tablet) If you are coming from an older 8" or 10" tablet then the Note Pro 12.2 will 'feel' much bigger but not much heavier. However if you are like me and never owned a tablet before while coming from a Laptop/Desktop background then the 12.2. will feel portable enough. In fact this tablet paired with the Zagg keyboard has already completely replaced my premium Lenovo Thinkpad for on the go Laptop duties. Speaking of Laptop PC Windows duties the Productivity Software that comes with the 12.2 is not the usual bloatware you would expect. In fact apps like Hancom and WebEx puts Windows Office to shame. These productivity apps put the practicality of Microsoft Office onto a tablet environment where everything runs smoothly (especially with S pen) without the costs, drama and high maintenance that you get with Microsoft Office products. I mainly use Hancom Word for writing (novels) and in this regard I recommend an external keyboard (like the Zagg) since the touch screen keyboard can hog some screen real estate. Other obvious positives to a 12.2 screen is that you can do way more stuff at the same time and this tablet does the job of multi windows smoothly. My only prior tablet experience was my fiance's iPad3 which interfaces only one app at a time. Having the 12.2 do more than one thing at once took some getting used to. It is fun and most practical. CONS: The 12.2 screen carries over the resolution from the Note 10.1's screen (why?). This means in apps like Gallery, Facebook and eBay some lower resolution photos do not scale up properly to fill out the bigger screen. Instead the Note Pro 12.2 tablet stretches out and enlarges images in these apps which results in slight fuzziness on those pictures. So if you are importing old school throw back pictures that you scanned back in 1999 then don't expect those pictures to look good here. On the Note 10.1 the same images would come out sharper on the smaller screen space. Lisa Gade at MobileTech has a brilliant side by side 10.1 vs 12.2 video on YouTube that shows this effect better than I can describe here. In fact isn't a big issue and most people who use hi-res pictures won't notice it at all. That said the camera on this tablet like all current tablets is quite crap compared to most high end cell phones or digital cameras. The camera app does have all the latest and greatest features but dont expect wallpaper quality pics. Use your samsung cell phone instead and import pics. Regarding the screen resolution I will add other apps like Adobe, Chrome/Internet, NYTimes and Magazine/FlipBoard have very crisp and clear images that are on par or better than iPad Retina's images so don't let that turn you away. My next gripe is in the box this tablet comes with nothing. You get the usb cord/charger combo, a quick start leaflet, and replacement nibs for the S pen. For $800 spent here I would have at least wanted headphones and a proper manual booklet (you have to search Samsung's website for the 178 page SM-P905 pdf file). Funny enough the SM-P905 manual when you download it has A LOT of important information regarding how to use this tablet properly. For one it warns "do not use a screen protector on the Note Tablets" which is the first thing we all buy for it. I use one anyway and it works fine with the S pen and touch controls. Be careful with where you buy your MicroSD card from. I went thru two eBay-bought SanDisk and Samsung 64gb cards, most likely fakes, that didn't work, died and almost damaged my Pro 12.2. I finally purchased the genuine Samsung 64gb card at my local Best Buy and it worked. Funny enough the eBay cards worked perfectly on my PC laptop and BlackBerry smartphone so that means the MicroSD card drive on this 12.2 tablet is very picky. One of my early concerns was out the box it took this tablet about 5 hours to charge from 70% to 100% and much longer to charge from near empty. To improve charging time I went to Application Manager->Running and deleted hidden background Bloatware like HP printer services, Blurb Checkout, etc... On kitkat 4.4 these sneaky apps remain running even after you sleep the tablet suckling away at your battery. With bloatware gone I now go from 30% to a full 100% charge in 4 to 5 hours. If that is too long for you then the LTE note pro 12.2 tablets will have batteries that charge much quicker but the downside is they will also die quicker than non-LTE models. Price was not a con for me but Samsung releases so many similarly priced tablets with a range of features that it makes me wonder if the Tab Pro 12.2 didn't come out at the same time would the retail for the Note Pro 12.2 be cheaper. Other than these minor gripes this is a perfect tablet for everyday use BONUS! ZAGG KEYBOARD REVIEW: I love that this keyboard works flawlessly, protects the screen when closed has great battery life. Also with its own leather stitched back matching the 12.2 perfectly BUT the Zagg is not a good case holder. The 12.2 lays facedown into the Zagg and clips on but the connection is loose and the tablet moves up and down inside the clips. Also removal of the tablet (as per the instructions) requires you to yank it up snapping back the holding clips open to release the tablet. The issue here is those clips are springy but still plastic and look like they will eventually break (I assume) from continued removal of the tablet. Furthermore you can easily pry or yank the wrong way and send the tablet flying across the room since it requires a bit of force. Also at $99.99 it is an overpriced keyboard accessory that isn't backlit and looks like it will wear out in a year or two of use. Already my spacebar key needs to be pressed really hard and in the center to work. I only purchased it at the time I picked my 12.2 because I needed a case right away and the only other case in Best Buy was $59.99. So I did the math and figured $40 bucks more got me a keyboard and stand for the 12.2. It does make a great stand. In retrospect I probably would not have bought the Zagg for more than $50 but I didn't really have a choice. It does its job with minimal features for the most part but do not expect a drop-proof case/holder or stellar desktop keyboard performance out of this product. 70 | R1WWQDXQOZ5LER 5.0 Lovin' my BAT 84 88 Samsung proves what the ladies already know, bigger is better. The 12.2 Note Pro has received a high percentage of positive reviews on Amazon and other sites. Most professional reviewers, on the other hand, seem to think it's just too big, too heavy, too expensive, or it's just not an Ipad. Fortunately for me I've learned to take professional reviewers with a huge grain of salt. Thanks to reviews from real users on Amazon and balanced reviewers like Lisa Gade from Mobile Tech Review I was able to take the plunge when the Note Pro went on sale. And I love my Big Ass Tablet (BAT)! I wasn't sure I could use that word in my review, but I did a search on Amazon and found out they sell this Liquid Ass So I guess it's okay. I've owned two 7" tablets, two 10.1" tablets, and I recently bought the Samsung Tab Pro 8.4". The 7" were good for portability outside the home, while the 10.1" were good for couch surfing. I thought the 8.4" would be a good compromise between the two that I could use for both, and consolidate down to one size. However, after using the 8.4" for about a month I discovered my eyes aren't up to looking at a small screen for several hours at a time (reading/web surfing on the couch is my favorite past-time). The 8.4" has great resolution, but text is still small and zooming in just means you have to scroll a lot. However, it is great for portability outside the home, and I will keep it for that. The 12.2" offers no compromise web browsing and document reading. Rarely do I feel the need to zoom in. I'm also addicted to the S-pen. Love to use it for navigating my tablet, and I also prefer to write with the pen then use the onscreen keyboard. I guess it's Samsung tablets for me, until the competition catches up and produces something better. Some people might complain that the tablet is too heavy for couch surfing. I've solved this problem by modifying the Aerb case I got for the tablet Aerb® X Pro Series Samsung Galaxy Note Pro 12.2 Leather Case Cover Stand W Sleep Wake Function (for Galaxy Note Pro 12.2, Black Style A) By folding the cover of the case and securing it with four small binding clips I can use the case to prop up the tablet while lying on the couch or in bed. Weight becomes a non-issue and I only need to lightly grasp the tablet with one hand to keep it from tipping over. I've included some pictures to show you how I modified the case, for those that are interested (see the user supplied picture area of this product's web page). So far I'm completely satisfied with this tablet. My only complaint is the price. Wish it was more like $600. Even so, I'm livin' large and lovin' it! I hope Samsung keeps making this size tablet. It's ideal for my use. 71 | R1T5127OGNXDR9 5.0 Simply Amazing!! 158 178 For those who've rated this low because of the size, do your research. Duh! It's a 12.2 inch tablet. I'm a cartoonist and really wasn't excited about spending $2K on a Wacom Cintiq Companion. I spent all of yesterday using this Samsung for drawing, web browsing, and calendar use. This is the best tablet I've ever owned and will use it daily. Yes, it's a bit on the expensive side, but for me, with how much I will be using it, and what I'll be using it for, I can more than justify the cost. 72 | 73 | As we could see the reviews are not properly formatted like a news article, few decisions were made for data preparation 74 | as mentioned below. 75 | 76 | ### Key Decisions in Data Preperation 77 | * Since the summarization task is extractive(not abstractive) from the original review file, only sentences with number 78 | of words between 10 and 30 are considered to avoid long story lines written by users in the final summary. 79 | * Only english alphabets are considered in the summarization process. All special characters and numbers are ignored in 80 | both methods implemented in this project. 81 | * Stopwords in english are ignored and all other words are lemmatized. 82 | 83 | ### Data Preparation 84 | 85 | * A review file of a product is collected into a reviewRDD as key(review_id), value(full_review) pair. 86 | * Each review in the reviewRDD is comprised of multiple sentences, so each review is further split into individual 87 | sentences, let's call sentenceRDD. Each sentence is identified by a unique key.(Here few sentences are removed by 88 | following the key decisions described above) 89 | * Process(remove stopwords, lemmatize) the sentenceRDD to extract only words that are meaningful. Here words with less 90 | than four letters are ignored with a heuristic that more meaning can be captured by longer words than shorter words. 91 | * The processed wordlist from the sentenceRDD replaces its sentences with a list of words to form wordlistRDD. So the 92 | id(key) of each sentence is preserved to its corresponding wordlist, which is used to finally extract the summary 93 | sentences after performing the summarization techniques. 94 | 95 | 96 | ## Summarization 97 | 98 | ### Latent Semantic Analysis 99 | 100 | After preparing the data as mentioned above, full `vocabulary/rowheader` of the review file is obtained from the 101 | `values()` of wordlistRDD and `sentence_ids/columnheader` from the `keys()` of wordlistRDD. From the wordlist obtained by data 102 | preparation, term-frequency vector for each selected sentence is computed and then using the term-frequency matrix 103 | the document-frequency( *here document means sentences in the review file*) vector is computed. Inverse Document Frequency 104 | is then computed using the document-frequency vector and total number of sentences. TF-IDF matrix is computed by multiplying 105 | TF matrix with IDF vector using numpy. Here the rows and columns of the TF-IDF matrix are words and sentences respectively. 106 | 107 | After computing the TF-IDF matrix, factorized the matrix by ***Singular Value Decomposition*** (using numpy) and collected the key 108 | sentences from the right singular matrix. The matrix decomposition resulted three matrices U, S and V-Transpose. U is the left 109 | singular vector matrix, S is the diagonal matrix of non-negative singular values sorted in descending order and V-Transpose is the 110 | right singular vector matrix. Latent Semantic Analysis summarization method chooses k concepts from the right singular matrix 111 | and in each concept(row vector in V-Transpose) selects the sentence with largest value to the summary. This method is 112 | suitable when we know the number of topics/concepts in a given corpus of documents. ***But in the review summarization task, 113 | since there is no predefined set of concepts, i've chosen 10 concepts with top 5 sentences each. So the concepts 114 | captured by LSA in final review can be interpreted clearly.*** 115 | 116 | #### Sample Output by LSA Summarizer for "Samsung Galaxy Note Pro 12.2" 117 | 118 | The following is the sample output which contains 5 sentences on each concept/topic in the review. There are obtained 119 | from the right singular vector matrix. Here, 120 | 121 | * **Concept X** clearly shows the positive feedback about Hancom Office that comes with this tablet 122 | * **Concept Y** describes about the screen of the tablet 123 | * **Concept Z** Captured sentences that described the keyboard and battery performance 124 | 125 | ``` 126 | Concept X 127 | [Sentence 1] : [u" Combined with any Bluetooth Keyboard and the Hancom Officer suite (it's free!), it's almost exactly like your Microsoft Office at home"] 128 | [Sentence 2] : [u'2 is first and foremost a pseudo-laptop replacement computer, especially when you have specialized office apps like the (full version of) Hancom Office'] 129 | [Sentence 3] : [u' - The Hancom office app is only a viewer, but you can use OfficeSuite, WPS Office or QuickOfficeHD to have a near 95% Microsoft compatible experience'] 130 | [Sentence 4] : [u' The Hancom office is very useful, I now have no need to get Microsoft Office 2013 for my laptop'] 131 | [Sentence 5] : [u' Samsungs free office suite is just like working with Microsoft office'] 132 | 133 | Concept Y 134 | [Sentence 1] : [u' Pros: Large screen Fast computing processing speeds / large amount of Ram Beautiful looking screen with large resolution Easy setup with secure packaging Highly customizable with smooth operation'] 135 | [Sentence 2] : [u'2: 1) the large screen allows for effective split window use; 2) the large screen is great for reading technical textbooks'] 136 | [Sentence 3] : [u" Apps do not transition well from full screen to partial screen, and most are nearly useless in quarter-screen, so don't put too much faith in that multi-app functionality"] 137 | [Sentence 4] : [u" The stylus is incredibly useful to write notes and the fact that the screen is so large really makes you feel like you're just using an actual notepad"] 138 | [Sentence 5] : [u' Second, the on-screen keyboard keeps popping up! The BT keyboard is connected and working, but any pen-clicking on the screen slides up the on-screen keyboard as well'] 139 | 140 | Concept Z 141 | [Sentence 1] : [u' Battery life: At first average battery life between charges was about four hours'] 142 | [Sentence 2] : [u" I've read however that those using the Logitech Bluetooth keyboard are now experiencing issues with their Logitech keyboards after updating to lollipop"] 143 | [Sentence 3] : [u' Second, the on-screen keyboard keeps popping up! The BT keyboard is connected and working, but any pen-clicking on the screen slides up the on-screen keyboard as well'] 144 | [Sentence 4] : [u' Now my Logitech Pro keyboard no longer works and the Samsung screen keyboard works randomly'] 145 | [Sentence 5] : [u" - Battery life and charging times could be better if you're used to an older Transformer that had a battery in the keyboard dock"] 146 | ``` 147 | **Note:** Few concepts showed redundant information, so selected only three concepts randomly(without following any order) for this example. 148 | Here X,Y and Z represents 5th, 3rd and 7th concepts respectively in the actual output. 149 | 150 | **We can use LSA to get the important words instead of sentences by doing SVD on transpose matrix of tf-idf matrix. I've added 151 | instruction below to choose between words/sentences while executing the program.** 152 | 153 | ### TextRank 154 | 155 | TextRank is a *graph based summarization algorithm* and this starts with the same data preparation steps as LSA till 156 | producing the wordlistRDD. Here each wordlist represent a vertex of the graph.

It surprisingly resulted sentences 212 | with very few words in the first concept which didn't give any meaning at all. 213 | * Then i picked sentences with words more than 10 words, this resulted with same long sentences appearing in multiple 214 | concepts(or rows) because longer sentences have more words and that can represent multiple concepts. 215 | * Negative reviews are mostly user specific, so they didn't show up much in the top concepts. Also the negative reviews 216 | are comparatively very less in number than positive reviews. 217 | * Text rank is pretty stable in this and always prefers sentences with more words and have more edges. 218 | * TextRank and LSA are not so good choice for text summarization, but these can be used as a step 1 for summarization 219 | task. 220 | 221 | ## Evaluation 222 | 223 | * Since the evaluation of the text summary involves comparing many human written summaries with the machine generated 224 | summary by checking unigram co-occurrences, i've not evaluated these two methods. 225 | * Also the commonly used tool for evaluating summary '[ROUGE](http://www.berouge.com/)' was written in Perl script and 226 | limited time didn't allow me to explore the usage of the tool for this task. 227 | 228 | ## Installation 229 | 230 | ### Dependencies 231 | 232 | * Python 2.6 or 2.7(not tested in 3.x) 233 | * [Install pip](http://pip.readthedocs.org/en/stable/installing/) 234 | * Numpy(version >1.4) 235 | * NLTK Library 236 | * Apache Spark 237 | 238 | #### Install Numpy and NLTK 239 | 240 | ```bash 241 | sudo pip install -U numpy 242 | sudo pip install -U nltk 243 | ``` 244 | 245 | #### Download Stopwords from nltk data source 246 | 247 | ```python 248 | #Pythonic way 249 | import nltk 250 | nltk.download('all-corpora') 251 | (or) 252 | #Command line way 253 | python -m nltk.downloader all-corpora 254 | ``` 255 | 256 | ### Execution Instruction 257 | 258 | #### Summarization using LSA 259 | $ spark-submit lsa.py -s 260 | (or) 261 | $ spark-submit lsa.py -w 262 | 263 | Note: -s and -w flag returns 'review key sentences' and review 'key words' respectively. 264 | Example: 265 | $ spark-submit lsa.py -s hdfs-path-/dataset/reviews/B00HWMPSK6.txt 266 | 267 | #### Summarization using TextRank 268 | 269 | $ spark-submit textrank.py 270 | 271 | Iter-count - No of iterations for textrank algorithm. 10 iterations give results close to converged state 272 | summary-sent-count - No of summary sentences as the final result. 273 | 274 | Example: 275 | $ spark-submit textrank.py 10 10 hdfs-path/data/reviews/B00HWMPSK6.txt 276 | 277 | #### Output Interpretation 278 | 279 | Outputs of the above execution will be saved to a text file in the following directory as well as 280 | printed on the console(Disable logs to get clear output). 281 | 282 | yourHDFShome/output-lsa/ 283 | yourHDFShome/output-textrank/ 284 | 285 | Example: 286 | $ hadoop fs -cat output-lsa/* 287 | $ hadoop fs -cat output-textrank/* 288 | Note: Delete the output folders if you would like to check again with different input file. 289 | 290 | ## Source Code 291 | 292 | ***Not available for now*** 293 | 294 | ## References 295 | 1.

Keep in mind, this tablet is $50. I am surprised at the functionality of such a low priced system its not a Samsung, iPad, or amazon fire, but what you get for what it costs is perfect. This tablet is great for checking email, surfing the internet, playing some games, watching YouTube or streaming twitch. Multitasking will slow down the tablet, so try not to have multiple apps open and running at once. The screen resolution is OK, its not high quality HD but its decent. It plays simple games just fine, solitaire, word search, chess, etc just fine. Higher quality games work also but the most graphic intense will cause some stuttering. I tested using Need for Speed : No Limits and it ran pretty well, only a few seconds of stuttering during the most intense parts. YouTube and twitch video streams play just fine. Surfing the web is smooth, I tried the stock browser, also chrome, and maxthon. If you manually adjust the screen brightness to middle, the battery life is great. I am able to watch 1 hour of videos, read a book, surf the web, and write this review and battery is at 67%. I have yet to try the built in Bluetooth feature. Runs Android 5.0.1 You will have about 4gb of free space, but there is a slot for a microSD memory card. The BAD: The cameras, front and back are really low quality (but its $50) The speaker, not very loud. Tiny hollow sounding (but its $50) The build quality, feels very cheap. (but it's $50) I recommend this tablet as a great replacement/backup tablet, a tablet for seniors or Kids. If you want to take or edit high quality photos or videos, play the most system intense games, or work within 3-4 apps all at once this isn't for you. 2 | RN0FLPVQ6JZM6 5.0 Awesome, Elegant, Nice, Tablet that works VERY WELL!! 33 37 ****Product Received in Exchange for Honest Review**** This is another GREAT NeuTab tablet.. This is probably their most elegant and most vibrant screen tablet on the market.. This tab is called the Air7 I assume because this tablet is designed to be similar to an Apple Ipad.. Pros: 1.) Power: This tablet offers a Quad Core processor and 1 GB Ram meaning this tablet has plenty of power for basic gaming, using with drones, photo editing, and more!! 1.) Quadcopters & Drones: I tested this with the new DJI GO app (Downloaded from DJI directly) and also with the 3DR app for opensource quads... This tablet worked EXCELLENT FOR THAT 2.) Games: I downloaded all 10 of the top 10 games to see how this tablet performs.. I know most new tablet owners will probably play at least half the top 10 games when they buy a new tablet.. It performed great and played all those games with ease!! No freezing.. No shuddering.. No performance issues at all 2.) Battery: GREAT BATTERY LIFE. About 8 hours standard use.. Several days with basic use.. And about 4 hours with VERY HEAVY use.. I have no issues with the battery of this tablet.. 3.) Design: This tablet offers a very excellent design!! It is built with a VERY NICE metal backing. The tablet doesn't feel like a budget tablet!! It feels like a very premium design and is built by very premium materials!! This tablet is impressive for the price and looks as nice as an Apple product.. I really love the design of this tablet a lot! 4.) Android 5.0: Android 5.0 is preinstalled!! Very modern UI and very fluid OS.. Android 5.0 works GREAT on this tablet 5.) Sound: Sound comes from one speaker on the lower back of the tablet.. The sound quality out of the speaker, while not the best, is pretty good.. 6.) Screen: with the new kindle fire coming out, these low end tablets are going to really have to improve their screen quality.. NeuTab has done that here!! The screen is VERY BRIGHT.. The screen is VERY VIBRANT.. This is the best 1024 X 600 I have ever seen!! I have recently been testing a lot of tablets and I have seen the screens improve greatly BUT this is the best I have tested to date! It will be very interesting to see how this screen compares to the new Kindle when it comes out 7.) Nice Packaging: Nice packaging always makes a GREAT GIFT 8.) Wifi: Wifi has excellent range.. It works GREAT.. I have no issues with Wifi 9.) Expandable Memory: This is a great option that is very hard to find on most of the current high end tablets but it is also something coming back on most of the newer high end tablets that have been announced.. I am glad to see tablets that offer expandable memory and the expandable memory in this tablet works GREAT!!! 10:) IPS Screen: This IPS screen doesn't have the viewing angles of some but it does have very wide angels.. I was very impressed with this IPS Screen!! 11.) DOES HAVE GPS and Bluetooth and BOTH WORK GREAT!! 12.) Value: All of this for under $60??? 13.) US customer service.. This is always a plus!! Overall: I highly recommend this tablet for anyone looking for an inexpensive tablet that looks great and preforms well.. Anyone needing a basic tablet, or a tablet for kids, or just a second tablet should be very happy with this!! I am very glad to see these generic tabs really stepping up their game!! With the new $50 amazon tablet coming out, I am sure these generic tabs will continue to step up their game and continue to improve!! This tablet is awesome, looks great, and performs well!! This tablet is very nice looking and when using this tablet I don't believe anyone will be able to tell this is a generic tablet from China 3 | R1NQKOGLIYJCXM 5.0 Nice build quality and performance 24 28 PROs + Quad Core Processor: Whether your checking Facebook or playing games, a responsive interface is important. No one likes delays or "stuttering" when trying to scroll a web page or start an app. The NeuTab Air7 comes with a quad-core processor. It may not be top-of-the-line, but I found general web surfacing and app loading to be very good, with only occasional hesitations. Some games do run choppier than they would on other tablets, but the Subway Surfers game showed in my video performed very well. The Geekbench multi-core score came in at 816. + Build quality: Despite the name, the NeuTab Air7 doesn't have the ultra-thin profile of the iPad Air, but it does have a solid construction and the back is mostly a brushed aluminum finish. It feels very durable and the brushed aluminum gives the tablet a professional look. + Android 5.0: I was happy to see that this tablet came with Android 5.0 out of the box. Google's latest operating system features a new user interface, multiple user support (and a "guest mode" to prevent those who borrow your tablet from snooping through your apps), and battery life optimizations. + 8GB of storage: This refers to how many apps, photos, videos, and music files you can store directly on the tablet. However, only about 4.1GB is usable. If that's not enough space, you can expand the storage with inexpensive Micro SD cards, like the ones you would use in your phone and some digital cameras. The slot is located on the back of the unit underneath the plastic portion. + IPS Display: It's not very often that you find an IPS display in a budget tablet, but NeuTab includes it with the Air7 and it looks great. IPS means that you can look at the display at an angle and it does not appear to be washed out or "reflective". This tablet has a colorful display and an appropriate 1024x600 resolution for web browsing and many games. It doesn't have a Retina resolution, but it is widescreen and works fine for watching Netflix or Crackle. + Built-in GPS chip: You can load this tablet with an offline GPS navigation app and use it without data connectivity. The built-in GPS chip allows it to function like a dedicated GPS using satellites (instead of relying on WiFi triangulation). + Bluetooth: This tablet also has Bluetooth so you can use it with Bluetooth keyboards and Bluetooth speakers. Sometimes Bluetooth is omitted on lower-end tablets, so I'm happy to find it on this tablet. + Two cameras: I couldn't locate the specs of the cameras, but there is a camera on both the front and the back. Low light performance is not great, but the front facing camera is fine for a Skype video call. I wouldn't depend on taking stellar photos with the back camera, but it's nice to have the option to grab a quick snapshot. CONs - Speakers: The sound from the speakers isn't the best, and sounds quite "tinny". But thanks to the Bluetooth support, you can pair it with a good Bluetooth speaker if you want to listen to Pandora, Google Music, etc. Or you can plug in your own pair of headphones using the headphone jack. - Cameras: While I like that there are cameras included on this tablet, they are low resolution and the picture quality is poor in low light. However, its better than having no camera for quick Skype calls. Overall, I'm impressed by the performance and build quality of this unit given its "budget" tablet price tag. While it's not as powerful as some other (more expensive) tablets, it is great for checking Facebook and playing games NOTE: You may notice a Chinese app titled "Weibo" installed. Do not worry, it is not a malware. It is a popular social network in China. This app is not built-in to the ROM and can easily be uninstalled like any other Android app. * A free review sample was provided to me, and I strive to provide an unbiased and useful review to help you make an informed decision. 4 | R8JMPB94CCI64 4.0 A Very Nice Affordable Tablet 10 11 I was trying to make up my mind between the new Amazon Fire 7-inch tablet and the NeuTab Air7. After going back and forth on the decision for several days, I landed on the side of the NeuTab. First, a little background. We owned an Amazon Kindle Fire HD 7" previously, and disliked the modified Android OS strongly due to having to jump through hoops to get it to play online videos by installing Dolphin browser and Flash Player, needing to installing apps so we could read ePub books, not being able to access the Google Play store, plus an ongoing problem where the tablet would not charge fully and show zero percent, it would occasionally turn off by itself, and other random glitches. All of these reasons pushed us to try Neutab. The NeuTab Air7 is a nice looking tablet that looks more expensive than its bargain basement price. The back is made out of brushed aluminum, which gives it a classy look, and the weight and size of it fits very well in the hand. The quad-core processor makes this tablet very responsive. Opening apps, streaming videos, playing games, and surfing the Internet are quick and snappy with no observable lag. Resolution on the screen is sharp, and details are nice and crisp. Although there are slightly higher resolution tablets out there in this class, you may find it hard to tell the difference. If you are a pixel wonk, this may bother you, but the 1024x600 pixel display is good. And we did compare it next to a higher resolution screen, and the difference is negligible, imho. The camera, both the front and rear, aren't high-end, but for quick snap shots, it'll do the job. Just don't expect iPad quality. Speaking of the screen, we saw an overall greenish/cyan tint over the whole display. This was particularly noticeable when viewing skin tones on movies or looking at photos; the colors weren't true overall. I like photography so color balance is important. However, I was able to fix this issue easily by simply downloading an app from the Google Play store that allows you to add color correction to the display. It worked perfectly and now all the colors are good. Speaking of Google Play, (nice segue, eh?) because this tablet runs on 100% Android and is not adulterated or customized in anyway, this means you get the full Android experience. You can access the huuuuuuge app library at the Google Play Store and get stuff you wouldn't otherwise be able to download if you were running a modified version of Android. This also means you're free of "bloatware," programs, apps and features that you don't really want. The NeuTab Air7 runs on the latest version of Android, which is 5.0, aka Lollipop. I like the new settings interface, and other nice upgrades to it. Operationally, there are a few new things to learn, but if you're comfortable with Android, you'll be fine. You can add additional storage space by flipping open the flap located on the back of the tablet. A nice touch. The NeuTab Air7's volume isn't as loud as I would like, even at the full setting, but if you're just watching videos by yourself, it should be just enough for this purpose. If you want the full sound treatment, just bring out your own set of earphones, plug it in, and you're good to go. For the price, there is a lot of value here. Plus, this tablet has a 1-year warranty, unlike other tablets that only have a short 90-day period. This tablet was for a family member and I set it up for her. As a tech guy, I really like this tablet. And I liked her's so much that I am planning on buying one too. 5 | R2EU55Q1FD7Z0J 5.0 Love it! 13 15 This tablet is exactly what I was looking for! I wanted an affordable tablet to browse the Internet and read my online textbooks for school without having to carrying around my laptop or squint at my phone. Pros: I thought it was easy to set up and navigate. It's lightweight and fits comfortably in one hand. The design of the device is great. Webpages load quickly. Picture quality on the web is good. The cons would be the touch screen is a little slow to respond. I haven't used a stylus with it so that might make a differences and the built in camera picture quality is not good. I haven't used the speakers yet. I am not into technical jargon so I can't elaborate on any of those components. If you are new to the tablet world (I might be the last person to get on board) and want to see if it is something you would use a lot but don't want to spend a ton of money. This thing is wonderful! 6 | RVBM2L2UL648F 5.0 You CANNOT beat this tablet for the price! Better than most that cost DOUBLE!!! 6 6 You cannot beat this little tablet in double it's price range! I was very skeptical before my purchase, decided to give it a shot and now pleasantly surprised! I've owned many Android tablets, phones, & desktops, so I am not a newbie to the typical performance of Android devices. This may not be a $300 top-of line performer, but it's better than most at twice the price. In fact, I ended up replacing my brand-new ASUS ZenPad 8.0 tablet with the NeuTab Air7. It actually performs better & is more responsive than the ZenPad which has twice the RAM & faster INTEL processors. I also find that the display is more clear, sharp, & fluid than the ZenPad. The display is on par with my $200 Samsung 7" Galaxy Tab. The only things I can find a tad bit lacking is the sound and the hard-buttons. The sound is waek (as in not quite loud enough) since it fires to the rear out of one small speaker. The hard buttons (power & volume) would be better of they weren't quite so flush to the frame. This is a personal preference. I suppose the good thing about them being flush (no protruding) is that it's less likely that they get pressed inadvertently. One last minor downside... I am a big fan of portfolio covers on my tablets, but I do not like the universal models and universals are about all that you can find for this tablet. I am willing to pay a little more for a good fitting & secure cover. I would buy this tablet again and twice on Sundays without hesitation. In fact, I think I'll get the 10" model today and give it a whirl. 7 | R23DTLSOKRL6AY 4.0 Would be 4 1/2 stars if possible! 5 5 I have only had this tablet for one day, but I'm already so impressed. There is nothing this tablet can't do once its hooked up to the internet. I'm even writing this review on it right now! I have an android pay as you go phone and with it being my first android device and not being to grand, I was worried. To be fair some of the problems with my phone, like its battery life, are my fault do to overcharging. But even still it is very slow and freezes a lot, but not this tablet. I haven't had a problem with it yet (though its only been a day). Runs smooth, I've downloaded every app I wanted, charges and starts up fine, screen is bright and clear and beautiful (it nearly blinded me the first time I used it). There are a few reasons it is missing half a star but to me they are small reasons. 1. The camera isn't great. Its kind of blurry, but while I wanted a nice canmera, it was a luxury not a neccesity. I couldn't find the specs for the camera before ordering, but again I still liked everything else about it. I will post a picture taken with the camera with this review. 2. The screen is 7 inches tall but only about 4 and a quarter inches wide. I'm sure that's normal but its hard for me to hold onto and get a grip on because it seems oblong shaped. Other than those thins I can't think of anything I don't like about this tablet. Well worth 60 dollars. If you want a tablet but have little money this is your best option. 8 | R25PMWINKAIT9B 4.0 Great Tablet, Great Price 5 5 I bought this product for my teenage son in order to replace an older model tablet. Immediately after powering up the NeuTab Air 7 tablet, my son and I were both able to tell a difference in the quality of this tablet compared to his last one. At first, my son was slightly disappointed at the white color, but once he saw the metal back, he changed his mind. The speed is great and the software runs perfectly. The only concern I had was when we pulled it out and looked for the sd slot. We were not able to find a place for external storage. After checking online, we were thankfully able to find the location of the slot, but the book provided with the product was not helpful in the matter. I would definitely recommend this tablet, not only for the price, but for the quality. 9 | R1UKTH5FJQT3ED 2.0 Died within two weeks 5 5 I originally gave this tablet a 5-star review but am now reducing it to two stars. This is because my tablet died shortly after getting it. It refused to power on. Amazon graciously took it back. Since then I've purchased a Lenovo tab 2 which does cost about $50 more but is definitely worth it compared to this tablet. The Lenovo is much quicker much prettier display and sounds fantastic with front facing stereo speakers, has longer battery life and charges faster as well. It is just overall a much better tablet. 10 | R10MWX1WFMAPXN 4.0 I'm an old guy and spent a couple of easy hours setting up this new tablet up with my ... 5 5 Received the NeuTab Air 7 yesterday. I'm an old guy and spent a couple of easy hours setting up this new tablet up with my email accounts and transferring all my bookmarks and personal info. It worked great right out of the box and performs as advertised. Very happy and would say it is a very good deal for the price point paid. It is a lot thinner and lighter than my old 7 inch tablet that finally gave up working. 11 | R3JABW3IPYPDH5 2.0 Good value tablet - questionable compnay 4 4 Good budget 7" tablet. Camera is fine, not high end, screen is decent, not going to look like a Galaxy or iPad...zooming in on text, you'll see it the lower resolution come into play. Processor is decent...does take a bit to boot up but once you're in its fine. Mine does not run hot, and the battery life is strong out the gates...will update later if anything changes. I don't plan on using this to watch movies or play first person shooter games...I use it for an offroad GPS device. I searched for a while for the perfect unit and this is what I came up with. Didn't have to pay for the other version's mobile 4G chip, only wanted wifi and GPS. This tablet is going to compete with something like the 7" Samsung Galaxy Tab 4. Similar resolution, and specs, but 38% of the price. This tablet won't compete with a Samsung Galaxy Tab S 8.4 that has a very nice camera and super high resolution. But for 6X the price... NeuTab sends a little bribe with the tablet, saying if you review the product they will send you a protective case for free. I followed the steps and haven't heard or received anything. I'd be very mindful of this when reading other people's reviews. 12 | R1513ND2C7YW0K 5.0 Great little tablet! 4 4 This little thing is beautiful! I wanted a low-cost, very portable tablet running Android so I could edit google docs wherever I was, and this is the perfect device. I added a bluetooth keyboard case and I have a mini computer that is easy to bring with me wherever I go. 13 | R173QF12M04QRB 5.0 I can honestly say it was the best $60 I've spent in a while 4 4 I can honestly say it was the best $60 I've spent in a while. It is not meant to be an iPad replacement but is perfect for the coffee table. I use it for the web and video and it does a great job. I would recommend this to friends and family. 14 | R3HQHDOOWMC72Y 5.0 VERY GOOD TABLET!!!!! 3 3 I have to say that this tablet is very good and it has many feature that a $200 tablet. It contains many features like being able to connect a micro USB to USB and a micro SD card. This tablet is perfect for everyday use like reading eBooks,News and playing simple games. Also its awesome because you can download apps from the play store too and its already installed. But this tablet doesn't have the best camera but its a 65 dollar tablet. Overall i think this tablet is a REALLY GOOD TABLET. Pros: -Very light weight and good looking -Fast for web and casual games -Play Store already installed -Micro SD card -Micro USB to USB -Fast and snappy -Long Battery life -Includes Bluetooth -Bright display Cons: -Not the best camera -Slow charge -sometimes lags 15 | R2L3J3KN50ISMH 5.0 Best in class 3 3 Having used this tablet for about a month now, I can honestly say this is the best you can get at this price. It's no iPad or galaxy, of course, so don't expect ultra high resolution or all day battery. I have used other tablets in this price range and they almost always feel cheap and the screen is often on the unresponsive side. The Neutab Air7 is quite the opposite considering the low price point. The superb build quality along with the metal back make it that much better. Android 5.0 runs smooth and is nearly stock with very little bloatware. The only downside I have found is the included charger. It seems loose at the adapter and you have to get it just right to charge. I just use my phone's micro usb charger to fix that. Overall, a great deal. You can't go wrong for a basic tablet. 16 | RTDZP8GJIAU85 5.0 So much for so little. Best budget tablet out there! 3 3 So happy I went for this tablet. I mainly chose this tablet because of the metal build. The memory expansion is great! Android Lollipop is a must have! I upgraded all the apps and linked my Google account and I was good to go. Just replaced the stock launcher with Google Now Launcher. Gives it a more stock Android feel. The camera's are decent but not something I would buy for taking photos. The speaker is not very loud even at full volume. For $60, I don't think you can beat this tablet. You get a lot for so little. NeuTab has really surprised me with this tablet. I purchased 3! 17 | RXW3X9ZBDYLRP 5.0 Units are very responsive and fast - very good for a buck, there is nothing else to say! 3 3 Both tables arrived yesterday, kids are very happy so far. Very surprised about the quality and the product build. Units are very responsive and fast - very good for a buck, there is nothing else to say! Very surprised about the price, I paid a lot less for both tablets then for one iPad mini my respect here! Even if kids brake one it worth of buying again. We are talking about $60 tablet vs $300 or more. 5 stars so far! ***** 18 | R1DQX3US4Z0U6W 2.0 Not good for someone new to tablets. 2 2 The NeuTab Air 7 is not very easy for someone who is just starting to use tablets. There is a generic manual that comes with it that is not very detailed at all. In fact, the screen doesn't seem to match at all. It is slow to respond a lot of times. The keyboard needs to be fixed. I go to touch one letter and wind up with another. My regular stylus doesn't want to work on it. It says in the instructions, what little there are, to use a stylus designed for a capacitive touchscreens. I don't even know what this means! I have had to fight every inch of the way to get anything on this. If they made a manual just for this tablet that would explain things in simple English, it would help a lot, I think. I have been thinking about returning it, but my son-in-law wants to see if he can figure it out first. I would give this maybe 2 stars at the most. Edit on 24 Oct 2015: I have sent suggestions and questions to this company and have received no replies to them. I did however receive a nice case for it and I would like to thank them. I would also like to thank Fred Chapman for his feedback. It was very helpful on some things. I have managed to figure out some of the stuff since I received it, but it has taken much longer to figure out than it should have. If they had a decent manual for it, it would get the 5 stars because it is a very nice tablet for the price. Again, thanks Fred for the suggestions. 19 | R3Q28YDI6KGRZH 5.0 It looks good! 2 2 I am pleasantly surprised at the quality of this tablet. It works well and promises to do everything that I expected of it. The picture is sharp, and the sound is more than adaquate. I am anxious to test the GPS capability, because that is one of the features that sold me on this tablet. I shopped around quite a bit before purchasing this item. It's features and price caught my eye. I plan to share this information with my buddies. It looks good! 20 | RMQVPWPK7233Z 5.0 A third of the cost of other devices in it's class. 2 2 Has every feature that the higher-priced tablets have, for a third of the price. The screen is crystal clear and viewable from any angle. The metal back adds to the sturdiness of this device. The speaker is a little on the tinny side, but is clear enough to listen to music on. Came with Android 5.0 that was ready to go right out of the box. All-in-all, very satisfied with my purchase. 21 | RM7O39COX8I8L 5.0 good response speed 2 2 Affordable, good response speed, the camera is acceptable resolution and storage capacity is good, the applications work fine, is excellent, in short is a tablet whose quality goes hand in hand with value for money. Ergonomic, handy and functional design, the screen resolution is high quality, the color range is good. I am very happy with the product. 22 | RP0NVK4AQHVAL 4.0 Big bang for your buck!!! 2 2 This is my first tablet, but the image is very clear and the operations are smooth. My only complaint is that the front camera is a little blurry. But for $60 you can expect too much. I am very pleased with my purchase and I will be buying a second one for my wife. 23 | R1AF6U3RZ24K6K 4.0 SO FAR SO GOOD!!! GREAT $60.00 TABLET!!! 3 4 Just received this tablet!!! I wasn't totally confident buying an off brand tablet since I have had a Nook and Nexus 7 in the past. My Nexus died and I needed a new tablet, but couldn't really afford to buy a new one. I saw this. It only had 5 reviews and I only found one video about it on youtube. All the reviews were 5 stars though!! I got this in the mail yesterday and have been playing around with it. So far so good!!! It's a really nice tablet. I had Netflix on and the video did lag just a bit in spots, but nothing to bad to return tablet. I use it mostly for watching movies, tv, playing games and social media. It's an awesome value for what I wanted it for!!! I could never justify buying 400-500 dollars on a tablet. It's nice and light weight and fits in one hand easily! Now, I just want to get a cover/case and a Bluetooth keyboard for it. EDIT; If you are looking for a low budget tablet with only 8gb of storage this is for you. I got this tablet with the idea that it had an sd card slot so that I could add my apps and such to it. Unfortunately, you can only add files to the sd card. I was already running out of storage...:( Other than the storage issue, I didn't really have much trouble with tablet. It's nice looking and slick. Fits nice in the hand. I also thought the size just alittle too small for me and went with an 8 inch tablet. Netflix, YouTube, games, etc...all worked fine!!! I changed my rating to a 4 star because I still think it is a very decent tablet for the price. I hope this helps someone else. Customer service was very good. I emailed them and asked about the card slot and they got right back to me!!! 24 | R1WR3SYVZRIKR0 4.0 Great value, quite competent tablet! 1 1 You really can't beat the price. I noticed some complaints regarding slow boot up/having to enter the password in the middle of a boot with the related G7 and that is because these ship with encryption enabled by default - i've seen that on Panasonic ToughTabs before, but thought it was interesting that the user cannot disable it. There are numerous hardware similarities between this and the new 2015 Kindle Fire we got as well. The only thing we miss vs the 2012 Nexus 7 this is replacing is the magnetically triggered sleep/screen on feature and the variety of case selections. At this time, I'm not sure if the tablet has the magnet sensor to sleep or not, or if it's just that the only case Amazon has for this does not trigger it. Only remaining caveat is related to OS updates (if'/when this will support Marshmallow, or at least newer versions of Lollipop). One note: there is a very small hole in the frame on the lower left which is probably for the microphone. It's about 1 mm by 250 microns or so; fortunately, Amazon has a high resolution image of this tablet that shows the notch; otherwise I would have thought it was a manufacturing defect! Edit: The offer for a free protective case after leaving a product review was an unexpected perk! 25 | R2VUVGFJRA314S 3.0 Okay if you don't expect too much of it. 3 4 I've had this for a few days now, and used it quite a lot in that time. Pros: -Super low price, and that's great. -It looks pretty nice. -Hasn't broken down yet. -Good battery life. -Not too slow. -Android Lollipop -Has a micro memory card slot -Nice sharp display -Has the same lag whether you have one app open or twenty Cons: -It does have some lag anytime you tap on a button or icon, and takes a few seconds to get where it's going or figure out what it's doing. -The camera is absolutely abysmal. -Sound is kind of puny, but not too bad in comparison to the size. -Not as svelte as an iPad (which is perhaps an unfair comparison, all things considered). -It's kind of heavy. I'd hate to see what the non-"air" model weighs. :o) -The absolute worst thing is that the calibration of the touch screen is off, and I can't figure out how to fix it. When I touch the screen, the place that registers the touch is a couple millimeters lower than where I touched. This is super annoying and makes it difficult to play games or fill out forms, among other things. Overall, it's a decent tablet. If you're looking for a cheap tablet to do basic stuff, this will get the job done. But if you really love speed, an accurate touch screen, and super design, you might want to check out a higher-level model. 26 | R2V5L9X9KD6HAN 5.0 Good holiday buy. 1 1 I set out to purchase a entry level tablet for a relative for the holidays. I've owned a few 7 inch tablets and their performance and life span were middling to poor. Surprisingly this tablet worked quite well out of the box. I also like that it has a bit more weight to it than other budget tablets, making it at least superficially feel like more of a quality product than those I've purchased before. It's also barebones which is something I've never seen as far as tablets go. It is barebones in the sense of not having any bloatware or unnecessary apps installed, just the minimum Google affiliated apps you expect to see on an Android tablet. I've played numerous intensive games on it for the purposes of testing and found no lag so far. Even better is that that this tablet is running Lollipop (5.0) instead of KitKat (4.4), which is often what most tablets in this price range run on. Overall I feel like this was well worth my money considering some of the other options I had in the same price range being less powerful and having other issues 27 | R22JOO5J6D3XTA 5.0 Very happy 2 2 Very happy with this tablet. Small enough to easily take with you and has a big enough screen to see. Watching Netflix works really well. 28 | RS7Q43QA4VGCP 5.0 Too Good To Be True? 1 1 They say that if something seems "to good to be true," then it probably isn't. This item, and most importantly it's cost, proves that in some cases this statement is wrong. In most categories (speed, screen resolution, etc.), this will not measure up to tablets costing many hundreds more. But if you are looking for a good, solid, really inexpensive tablet, you will not go wrong with this. I would say that the overall quality and performance of this tablet is 85-90% as good as the other more expensive tablets out there. To be honest, given the materials, the labor, the packaging, etc. to produce this item, I cannot image how they can sell it at this price and make any profit. (I truly hope their workforce is not making $.10 an hour!) I will try to post an update after I have been using this tablet for a few months and let you know if I still give it the 5 stars. 29 | RMHJ6340Z09DK 1.0 It's OK 1 1 I'm not crazy about this tablet, but that's because I enjoy higher end gadgets! But! This was a replacement tablet for my kid who destroyed his Asus tablet and he loves it. The sound quality is very poor, not sure of its just my unit or what but it sounds like someone is sitting on the speaker. The optimist in me views this as built in volume safety lol and since I hate 90% of the game sounds that come from it anyway I don't mind. There are times the screen seems unresponsive to adequate touch. I probably would not repurchase this device should it break but it's a nice in betweener. A positive thing is that it comes with android 5.0 preloaded. And has 1 gig RAM! Definitely not a lot of tablets at this price range like this! Great for young kids that don't really care about more popular devices. Update 11/12/2015 Approximately one month after purchase, the tablet has died. Confirmed after leaving it on the charger all day and it never even charged. It will not even perform a soft reset. Will be returning device, that's if I still can! How convenient, I'm am 2 days past the return window. This company will definitely not be getting more of my money. Spend more for a better product! 30 | R1422HUW3YU2B 4.0 Just what I was looking for!!! 1 1 The perfect tablet for games, google searches, not heavy that's what I call a tablet, its lightweight for people with arthritis. If you get a tablet that is 9" or more I don't consider it a tablet, what are manufacturers thinking bigger is better? I just don't get it, that's just me I suppose. The only suggestion is not to put those little #'s on the top row of keyboard. Otherwise I am satisfied! Nice little tablet to upgrade to Lollipop. 31 | R1V6Q9X0TUAA1J 5.0 Great value for money 1 1 This is not an iPad or Samsung Galaxy Tab so don't expect it to compete, however it is an extremely competent low cost Android tablet which seems more than capable of meeting my needs i.e. a little browsing, occasional email, showing photos to my elderly mother. The camera is OK, the display more than adequate and it is reasonably quick. If your demands are not high end buy one today it really is good value for money! 32 | RMX6XGINQHOQY 4.0 Very nice and great price. 1 1 Impressive right out of the box. This tablet has the look and feel of a much pricier tablet. The glass touch screen was a pleasent surprise. The only thing I don't love is that apps cant be completely moved to the removeable sd memory, however I'm not sure if thats due to the tablet design or the android version. Overall 4 out of 5 stars especially for the price. I may even be purchasing a second one soon. 33 | RR7M2VBML1497 3.0 It's easy to use 1 1 It's easy to use. The picture isn't as good as I thought it would be. And the battery life on it is short if you don't power it down after use. I bought a case for a 7 inch tablet from 5 below and it is too big which I think is odd. I am a little disappointed but for the price it's really pretty nice all in all. 34 | R3C4AKZXYOTZU7 4.0 Great buy overall. 1 1 Excellent hardware and manual very much appreciated. But some icons in manual are different or do not appear on screen which is very confusing and frustrating. Otherwise I'd rate maximum score. I need to get used to virtual keyboard, my problem, not NeuTab's. 35 | R1TLE98MN2F9XN 4.0 Good for kids! 1 1 This was a good buy for my 5 year old, but I wouldn't recommend for an adult. It's a little slow & the screen is hard to tap. It holds a good charge & works well enough for my daughter to play her educational games though. And you can't beat the price! 36 | RMHLR39BF5HJ4 5.0 You get what you pay for and a bit more 1 1 Screen is really clear for a $60 tablet. Tablet is thin, lightweight and attractive. I had no problem downloading my favorite apps. Sound quality is decent even without headphones. Great for watching YouTube videos or surfing the web. Good purchase. 37 | R1RLZUJZXLT9SU 4.0 Good enough for the price 1 1 I needed a small portable device to take with me when I travel and have long layovers. This tablet was just right. Easy to set up. The keyboard was the perfect size for typing. The volume was a bit low especially for skype calls but not too bad. 38 | RZW8JEOT83CSD 5.0 A great tablet for the price 1 1 A great tablet (especially for the price), the screen is clear and crisp, easy to set up, wifi is fast. Everything works well - I haven't found fault yet. Comes with a charger, but works with any miniUSB charger. 39 | RR9NN3U1D0PXF 5.0 Just what I needed 1 1 Well built. Purchased exclusively for running square register for our business and this does the trick (note: app requires GPS on tablet and this fits the bill!) thank you! 40 | R3COFE1RII4HZG 4.0 seems to be a great product. Navigation is quick 1 1 Just received it, seems to be a great product. Navigation is quick, apps installed as a charm. The design is good, and the products fits perfect as a child present 41 | R1OJOLCDMOFTZ5 5.0 Works great! 1 1 NeuTab tablet is snappy and fits perfectly in my hand for a 7in tablet. Using it at work and love the new Lolipop feature to have multiple users. 42 | R2AUFSFMLMD6VH 5.0 Exatcly what I wanted 0 0 This is definitely worth the money. Just got this tablet a couple of days ago and it is meeting my expectations. I used to own a 10 inch tablet but it was to slow, barely able to watch videos and weighed to much to hold for long. with the 7 inch display and thin design it is light weight and keeps cool. Only having it for a couple of days now, been on it throughout the days and only had to charge it once so the battery seems to hold charge well enough. the Processor I feel does just what it needs, it plays the latest games without a problem,you can watch movies shows and clips in HD and with 8Gb of memory there's plenty for you to save. The screen is by far my biggest worry as reading everywhere on cheap tablets that this is a big problem. There is no screen problems on this great tablet, I can just about put it on its side and still see whats on the screen doesn't get better than that. So if your looking for a great tablet at a cheap price, as well as fast delivery then I wouldn't waste anymore time reading this. 43 | R3PY1CT1YH2EAU 4.0 Solid tablet so far 0 0 I haven't had much time with my NeuTab yet, but it is decent. I bought it hoping for it to be compatible with a few certain apps. Being the Android 5 OS may be why it wasn't, or the app is just very picky. For nearly $70 it is nicely made, feeling solid with a decent screen res. There is one con I can mention, that to me can't be excused because of the fair price, the volume and power buttons are not easy to find by feel in the dark. They are too subtle for ease of use. This also, on the other hand, prevents accidental presses of the volume button, not the power button, which stands out more than the former. I'd still prefer a more solid button press function. That having been said, doesn't take a star off. In my opinion, with my limited experience with tablets, it earns a solid 4 stars, 5 if the cameras were higher quality with flash function and if the tablet had a higher app compatibility. 44 | R33SZUSNBBSZ1X 5.0 Daily use, play, or work... worth it! 0 0 I bought two for my kids birthday and they love it. I tested it out myself first and was very satisfied with the quality. This comes with many options that compare to the more expensive tablets but for a better price that meets my budget.I was worried that some thing was wrong with the tablet, until I trouble shooted the charging issue. I would recommend that they work on better chargers to come with these tablets. We have one that I found was not exactly aligned with the usb port hole and some times won't charge unless you angle the male end of the usb inside the female port. I would guess that some people may find it not charging and quickly assume that the tablet may have a serious charging problem like I have read in earlier reviews. No matter the minor charger detail, I highly recommend to others to take the oppertunity and purchase this before any others. Good deal for kids and adults for daily use. 45 | R2WWVP0IYYBZ5P 5.0 So far I love this! 1 1 This NeuTab is just fit to my purpose, I just do internet surfing and watch youtube videos. So far I love this! 46 | R24E3DHMTSNGYO 4.0 NeuTab Air 7 Low Cost - High Value 0 0 First of all, this is a very good looking tablet with outstanding design features. While it is a value priced device it, looks and performs like a mid-range tablet. It runs on OS Android 5.0.1 (Lollipop). Most tablets at this price point run Android 4.4 (KitKat). Although it is an 8G tablet, it has a slot for a micro SD card for additional storage. This tablet is the perfect choice for a general purpose device that can handle all your basic needs in a beautifully designed package.NeuTab® Air7 7 inch Quad Core Google Android 5.0 Lollipop Tablet PC 1GB RAM 8GB Nand Flash 7" 178 Degree View IPS 1024x600 HD Display Built-in Bluetooth 4.0 Dual HD Camera GPS, Slim Metal Design 47 | R3HIZQXBNWLNU7 5.0 Five Stars 1 1 Very nice great price, excellent picture, totally impressed. Would definitely buy another one. 48 | R2FZBAFCPA6OZJ 4.0 decent tablet for keeping kids enterained on a budget 0 0 I was surprised with the tablets, I order two of them for my young cousins so they can play games. the games play as good as any other tablet, I was also very impressed that this tablet doesn't have any lag, I own two tablets and one is a Samsung Galaxy tab 10.1 which I stopped using because it has so much lag, but the NeuTab performs very well. the sound of the tablet was decent. the quality of the screen is not the greatest but you get for what you pay for. plus this tablet come with an OTG plug so you can plug any USB storage device to the tablet. If you are looking for a very basic tablet and you have a small budget this will work very well. 49 | R112QE9D655FVC 4.0 but am satisfied with everything so far 1 1 Haven't had much time to play with it yet, but am satisfied with everything so far. 50 | R3GJILNLG5KVEH 5.0 the best sister ever 0 0 this was by far the fastest shipping i have ever had and i am pleased to say that this blows my expectations out of the water it is fast clean clear display i ordered for my little brother for Christmas this year so i had time to test it out and with the intense graphics and speed required to run a game like asphalt 8 it was flawless in play through using the g sensor as the steering wheel no lag no glitches and brilliant display i am a tech girl and my go to is android and as far as androids go this is the best price for a really great product i cant wait to see him get this on Christmas morning 51 | R1NMP0KH96RUE2 1.0 This unit is misprogrammed and needs a better ROM. (I've been a Linux developer since 1994 2 3 Does not use a standard Android startup procedure so it never connected with Google properly. Never connected to my Google account in the contacts app. Yes, I rebooted. Yes, I did a factory "clean". Yes, I tried alternate contacts apps from the store. This unit is misprogrammed and needs a better ROM. (I've been a Linux developer since 1994, and I'm an embedded Linux systems developer by trade - I know what I'm talking about.) 52 | R1A24A3DIWEMZ6 5.0 It's good to me for the low price 0 0 It's my first Google android tablet. I have iPad, iPhone and Amazon kindle fire HD, so I tried this Air7 after lots of review, and it meets my expect. As this low price, it is very good for lots of function, especially offline GPS built-in. It's also nice look to me. For micro SD installation, I saw the Text explain from review and Q&A, but I still do not know how to do it since I'm afraid to brake it. If there is photo instruction to show how to install the micro SD, it will be better. Finally, I found the video how to take out the top backside cover to install the micro SD from one helpful review. 53 | R3EZB8ZIV8UGNH 5.0 Great buy!! 0 0 Great tablet! The package arrived quickly and on time and no visible damage. The tablet itself is really awesome and it works excellently! The camera is well made and we haven't had any issues with the processing or glitches. Compared to the other tablets we've bought or tried, this one is comparable and it costs a fraction of the price. We'll see how long it last with constant use by two young boys. I bought them for my nephews and they are rambunctious boys, but so far so good. 54 | RWTIWWA88T9T1 5.0 loving it 0 0 I got my air7 yesterday and so far I'm loving it. It was easy to open and set up. It is slim and light weight. It is just the right size for my smaller than average hands. It was fully charged. It doesn't seem to have any problems playing games or surfing the net. There is more than enough room for all the apps i already put on it. But if you need more room there is an sd slot. And I didn't know it came with fm radio installed, just another plus. Giving it five stars. 55 | R2RV2ZLC7KZMR5 5.0 Who knew? 0 0 When I ordered this I thought... OK... the reviews are good... but how good can a $60 tablet really be? Well spank my butt and call me Suzie. This is a great little tablet... you can't beat it for the money. Pros: Looks great Feels solid Decent screen Quad core 32GB Micro SD slot Cons (minor... but I'm a picky bastage): Don't much like the pre-loaded launcher A good case may be hard to find 56 | R2HJECUJOU961P 4.0 Worth the price but extremely slow power up. 0 0 The tablet works as advertised and is definitely worth $60. However, the power up time is incredibly slow, especially if the screen unlock is enabled. I figured 2 minutes or more. Given that most folks do not power off frequently, this may not be problematic. In my situation, the tablet was to be used only a few hours a week so powering off was prudent. Unfortunately, this extremely slow boot up process gave me reason to return the tablet. 57 | R2WH7JWPILQKK6 2.0 stopped powering on. 0 0 around a month later it wont power on. RETURNING. 58 | R3NW35XI0EM53N 5.0 so far, so in love 0 0 I got this for traveling and classes for notes, I haven't found an issue yet. I will keep posted though I want to help those searching for a good cheap tablet. It is a lower grade tablet in the sense of camera and graphics but I knew that when I got it. Its hard to find a case at my Walmart but I expect no less or more from my tiny wally world. I recommend though, from one cheap college student to the next. 59 | R2NB5NIL0LBIYF 5.0 with a nice picture to match 0 0 I had purchased this tablet for my younger brother, as he had been working off of a Kurio tablet for sometime now, and immediately after opening the box i could notice the difference. It runs very fast, with a nice picture to match, and at 7in. the size is not too bad, it is a light tablet, and ideal for carrying around with you. We have had it for at least three day now with no problems. 60 | R2CFT85X20FIZO 5.0 Kinda pretty looking, great screen, but I think I hate Lollipop! 3 5  HD version of this video is on YouTube, search for: Kilgore Air7 This video demonstrates playing media from an external USB flash drive with a paired Bluetooth speaker; IPS screen tilting showing excellent viewing from all angles; Google Maps with Local Street View; text entry with a Bluetooth keyboard; evil 2 minute 30 second boot up(!) explained below. This is a VERY nice looking 7 inch tablet which is probably my favorite size for "quick and dirty" and throwing in my bag. White and silver is a nice combo. The IPS screen is one of the best I've seen on this size tablet and really does allow viewing from lots of angles without that severe polarizing effect you get with the cheapest screens. My biggest complaint probably has to do with the Lollipop operating system - this is my first experience with it. A little research indicates that it has caused similar bootup problems as I'm getting. I put the bootup sequence at the end of my video (with sped up sections so you don't have to wait). It's taking over 2 minutes from turning on to booted up. Lollipop also requires what looks like a second "Bootup to Android" sequence after I put in my PIN. Once booted up I pretty much have no issues, except some odd happenings with Chromecast which is another documented problem area with Lollipop on some devices. I can Chromecast from YouTube, but can't cast my screen (that's still pretty much a beta feature anyway). So the tablet is an easy 5 out of 5 stars, Lollipop, not so much. Again, once booted up all is excellent to outstanding. I easily paired Bluetooth speaker and keyboards and used both without a hitch. Manufacturer gave me a free sample with no other remuneration nor review requirements. 61 | R28D0G064IAXIU 5.0 In love with it! 0 0 I recommend this tablet. I am very glad for making the decision to but it after my 2-year tablet died few months ago. I am very impressed with its performance for a $59.99 device. It delivers what it is promised. I just wish it to be compatible with whatsapp but that it is ok! So if you’re looking for a low cost tablet this is what you’re looking for! 62 | RE6C426AI4BV8 5.0 Five Stars 0 0 Works really well. 63 | RGCO7LW2DBXH0 5.0 Five Stars 1 1 I bought this for my niece and so far so good 64 | R1LX1NVL2FVVHQ 5.0 Lots of Bang for the Buck 0 0 This is a nice little machine. I got this for reading e-books, browsing the internet and watching videos. The screen resolution is not the highest, but honestly, I have no complaints. The screen is bright and videos play smoothly. Apps load quickly and work well. For this price, it exceeded my expectations. 65 | RWT9TKUYV30AL 4.0 Four Stars 1 1 product it as described...worth the money 66 | R9JH0NRBK23O0 5.0 Brand new tablet; package arrived as described and delivered ... 0 0 Brand new tablet; package arrived as described and delivered on schedule; So far I am impressed with its overall performance. It has the look, feel, performance and screen resolution of higher end tablets in its class and only under $60. I will check into their other products for they now have got my attention. 67 | R35JI6GWR5H7A6 5.0 Good quality materials with adequate internals 0 0 For the price I wasn't expecting Apple iPad quality. Bought for my 3yo and it is definitely worth much more than the asking price. Good quality materials with adequate internals. Basically getting a $150 tablet for $50. Great for basic usage but any more than that and you'll probably have a negative view of it. 68 | R3P6XYB9VDU4KU 5.0 Handy on Motorcycle Trips 0 0 Ordered this to take on motorcycle trips. Checking email is pretty fast. I haven't used the off-line gps navigation yet but will be testing that soon. The tablet was delivered on time and is as described. I think this is going to work well and is a good option to do away with hauling a laptop on my trips. 69 | R2RG8CJ9OK2BZR 4.0 Its a nice Tablet especially for the price 59 0 0 Its a nice Tablet especially for the price 59.99. Thin but has some weight to it. the only problem as of now is I wish there were more options for cases . it's alittle difficult finding an exact one. you have to do some detective work matching the buttons. other then that so far a fairly good tablet. 70 | R1NPL7KHUBSUC2 5.0 responsive and easy to navigate 0 0 This tablet was everything it claimed to be and more. It is fast, responsive and easy to navigate. Display is fantastic for it's price. I bought this for my grandson as a replacement and he LOVES it. I would highly recommend this tablet to family and friends as an entry to intermediate level tablet. 71 | R352VXTKRJF497 5.0 Very nice tablet for the money 0 0 Very nice tablet for the money. Also Impressed with the battery life. Processor speed and RAM are about what you'd expect for a tablet in this price range. I have no problems surfing the internet, playing games and using apps. It is light weight and well made. This tablet should last years. 72 | R25B619QVU86SC 5.0 Excellent product. 0 0 This arrived on time, and was just as described. I was looking for a decent, low cost tablet. It's not the fastest device out there, but the screen is crisp, and has decent battery life. It's superior to the 4 other tablets I've purchased in the same price range. Worth every dollar spent! 73 | R3UUBKIBPM0LYZ 4.0 So far so good 0 0 I had it for only a few days, but so far so good - everything works. The only thing, the manual is for the older version, so I could not find the task manager icon. It's actually the square one on the right of the home icon, which is actually a circle in the bottom center. 74 | R22CYF4R42ISM6 4.0 Good tablet for a good price. 0 0 This is a great value for the price. Bought for my daughter to use for games. It connects to the Internet well and is easy to use. The one drawback is the camera doesn't take very clear photos, but its not a high end tablet. Hopefully it will last for quite a while. 75 | R3GU7IMOPTXE18 5.0 NeuTab Air 7 is a winner 0 0 Very pleased with the NeuTab Air 7. Purchased it to replace my old iPad that Apple no longer supports with IOS updates and to use as a Remote for watching Hulu programs using Chromecast. Plan also to take it on trips. Very affordable and easy to use. It's a winner. 76 | R7RBD4FJ98VW9 4.0 responsive and the screen looks amazing! Only drawback is the speaker 0 0 Was pleasantly surprised by this tablet. For the money, you simply can't go wrong! It's fast, responsive and the screen looks amazing! Only drawback is the speaker, very low volume and a little tinny sounding, but still passable. All and all, money well spent :) Update: While this is still a great little tablet, I will be returning mine, due to the speakers. I just can't deal with the sound or lack thereof. If you're using this tablet with headphones or a Bluetooth speaker then you won't have a problem with this, but I don't. 77 | R1HLE9MQQW0CKQ 5.0 Very easy to use 0 0 Arrived on time. Very easy to use. Purchased for use at school. I like that the company promises that tech support will be easily accessible. If it continues to work well, we will consider buying other models as the price is very reasonable. 78 | RXV9IU89VXG8N 4.0 Great for kids!! 0 0 This tablet has great screen quality (for the price). It's sound quality isn't that great and picture quality is bellow average, but I don't use it to take pictures. It's great for browsing the web, streaming videos, and playing games. 79 | R11D31MIO9I2G8 5.0 I was happily mistaken😊 0 0 It works great!!! Love it! At first it wasn't downloading the apps... It is refurbished and I thought it was a gliche.. Gone unnoticed.. I had asked for return label... But after I plugged it back it has been working fantastic! 80 | R12BJMNW7AG463 4.0 Very good product. Its a good and durable tablet for ... 0 0 Very good product. Its a good and durable tablet for a fair price. I paid about $67 and I wanted something that served as a big remote for me as well as allowed me to use Android. This Tablet does just that for a solid price. 81 | R2P30C9SM2J40L 5.0 great tablet 0 0 Quick delivery, item as promised. Love this tablet bought it for my 9 year old but it's pretty nice, may have to keep it. Downloads great, nice display, great size overall great product, would definetly buy again from seller. 82 | R38NXQPG4DKEE3 5.0 Very Pleasantly Surprised 1 2 OK, I often read reviews, but seldom write them, so this product has to be good. I basically went out on a limb because it was a Lollipop Tab, and I needed to upgrade by Galaxy Tab 2 - on top of that the price was great. Just received it yesterday and spent a couple hours getting everything up to speed. I did get a couple of Google Play error messages, but aside from that - everything installed and synced very well. To my surprise basically everything I tried worked great - even the Optimum App which is very picky worked like a charm. The interface was very speedy - you tube videos play without a hitch, which is great as I bought this for a media entertainment tab. I'll add more once I have it for a month or so - but for now it is great. 9-30-15 Update After a week of usage, a couple of things could be better - buttons are a bit tricky to push at times, and inserting a SD card could be easier, but my view on performance has not changed. Battery is OK - will need to monitor it more closely. I'll be taking it on vacation next week, so I'll see how it works as a road warrior. Still very good, would actually rate it a 4.5 because of the buttons and SD card handling, but I'll round it up since the tab's performance is really good. 83 | R3P8KXMDM8E6TI 4.0 Great tablet for the money. 0 0 So far so good. I do have a slight issue with the touch screen. At times it seems to be rather hard to get it to do what you want it to do. Actually that is a minor flaw compared to everything else. So far I love it. 84 | R3I0ZINK01PUVD 5.0 Very good 0 0 This is a great little tablet. The graphics are high quality. It works with no delay and is very quick. This is a really good product for a reasonable price. I think this is a nice alternative to the Fire tablet. 85 | R2DPPWWQIMHHZ5 4.0 Good Tab for great price 0 0 Good Tab for great price. I got this tab as an award for writing the best parallel program in class. This is perfect for me because I want write low level programs on this tab. Quality is good for this price! 86 | R2E1AEHX91SXAH 1.0 Pretty sure it comes loaded with malware 0 0 Week after using tablet I started getting popups. Has Broservice and Linervice running on it. I did a factory reset and those programs loaded again. Has the same apps that are in my cell phone. Pretty sure it comes loaded with malware and adware. Found a service IMeMess running after factory reset and I think it's the program that downloads and installed the malware. Part of Backservice which loaded the programs on startup after I disabled them from being allowed to run at startup. 87 | R2JVIREI461SJE 4.0 it's a good deal. Mine came with a small scratch on ... 0 0 For the price you are paying, it's a good deal. Mine came with a small scratch on the screen. I can watch videos and read without problems, but that scratch bothers (more taking into account that is new). 88 | R1DKC05HOQ62NI 5.0 ... year old nephew for his birthday and he absolutely loved it.

It is simple enough for him to use alone but also has everything they would need as a family. Couldn't be happier! 89 | R1US1EGY3BOLWK 4.0 good enough 0 0 Its not what i was wanting but its pritty cool for what it is....the charger plug in sucks though one of the prongs fell out in my outlet & the charging port stretches out REALLY EASILY. 90 | R3PMHEACAS5Z1U 4.0 So far so good!!

My tablet arrived, I opened it, & it was completly dead, so I plugged it in, and set it aside, then a fews hours later I turned it on, and a huge red "X" went across the screen, and it wouldn't turn off or do anything! It was such a dissapointment! I'm a single mom, & on a budget, how could they sell products like this? It's not right. 157 | R1SKLCC7YXGPIF 5.0 Five Stars 0 0 great deal! 158 | R2A7TF7PAYZJ0O 5.0 Five Stars 0 0 Good value. 159 | R2IU6URJ0V69PS 5.0 Five Stars 0 0 good tablet 160 | R1V16RAZC6ARWM 1.0 Amazon makes returns easy but it's better to spend a little more on ... 0 1 The tablet only worked for a short while...the keyboard and icons started to malfunction...you push on an icon or letter and it would go to another icon(s) instead of the one I was pressing...not worth the money nor the hassle of having to ship it back for a return...Amazon makes returns easy but it's better to spend a little more on a better tablet and not have to worry about it malfunctioning. 161 | R2V7OHQ48QXMN5 5.0 Five Stars 0 0 Fantastic! 162 | ROOWLXDA67TYC 3.0 nice setup, 1 2 So far it a good tablet, my Son love it. 163 | R1T2KW1FV1VZK 5.0 Five Stars 0 0 Worth it 164 | RY3F2VVDRA704 1.0 The real sad part is that they tell you that u can ... 1 3 First I must say delivery was on time,just as seller promised. For the price,I think it's reasonable, However I don't think that this gives the manufacturer or seller the write to be dishonest about its functionality. The specs is not consistent with what is actually written in description. Whenever you download apps it goes direct to internal memory, so you have limited storage for other stuff. The real sad part is that they tell you that u can add additional storage via a sd card. Because of what they say I purchased a 32g the same time. To my surprised,when I try to transfer videos /files to my sd card it failed. I even try to reformat card on a desk top,load files and videos on card first, then placed back in device.after that, it's telling me,"not compatible. The volume is also very poor,more like a head phone speaker. Even a cheap cell phone speaker is louder than this. I also purchase a 4g lte g7 version,so I will see if they lied about that one also Very frustrating. 165 | R1BHJ9K776095E 5.0 but up to now its hss proved to be a good tablet. Excellent for the price 0 1 Heve not played with it a lot, but up to now its hss proved to be a good tablet. Excellent for the price. Nothing against it yet. 166 | R2S2Q5N0KDRM84 3.0 reasonable power, terribad screen 0 2 I returned this becuase I don't like the IPS screen. Also, it has software nVbar which eats up massive amounts of the terrible 1024*600 screen. The other hardware, like the CPU and GPU are pretty great, and the touchscreen is multitouch. I just realized that I could spend twice as much and get a tablet 8 times as good. 167 | -------------------------------------------------------------------------------- /data/reviews/B016POG0L2.txt: -------------------------------------------------------------------------------- 1 | R27E04YNNBMHGK 5.0 Best iPad Mini yet 16 18 I've really liked the iPad mini from the start but in the beginning they were filled with old parts and the speed and capabilities left a good deal to be desired. As they came along they added better screens, then better processors, then touch id, then more RAM. The iPad Mini 4 is wonderfully compact while offering a fast and powerful tablet with very good battery life. With the new hardware they have enabled true side by side multitasking which may have come late to Apple products but it works great and is a welcome addition. It is just a great tablet in general. The screen looks amazing and especially compared to older model Mini's. The processor makes everything very quick and snappy. The added RAM makes multitasking and using a bunch of different apps usable and viable. The new rear camera is improved and you can now even take slow motion video with it although I personally never use the cameras on my tablet. One of the best features for me has always been the battery life. I've owned a few different iPad's now and have always been impressed by the battery life. I don't think I've had a single one that gave me under 10 hours of battery life if not a few hours more. This iPad is no different. Is it the tablet for you? Maybe. If you're in the Apple Ecosystem already, if you are coming from an iPad Mini 1 or 2, if you have an iPhone and want your first tablet, if the price of admission doesn't bother you, then yes. If you're not in the Apple ecosystem and you just want a good tablet, there are definitely other options with similar features. The Nexus tablets have always been very functional and capable at very reasonable prices. The surface tablets are super functional and capable at a range in prices. What it comes down to is use and what you're using and willing to spend. If you're like me and regularly use a desktop at home and a tablet for travel or for sitting in front of the tv playing games, checking and writing email. looking at pictures, or surfing the internet, then you can't go wrong with this iPad or a comparable Nexus. Even the $50 fire tablet would be a great general use tablet and impossible to beat at that price point. If you use laptops and want to replace it with a tablet pc, then the Surface Pro or even the new Surface Book will nicely fill that roll. The iPad Pro might also do that but the jury is still out on that one. In general this is a great upgrade for the iPad Mini and it is easy to recommend if the price doesn't bother you. UPDATE: Still enjoying the new Mini but wanted to point out that the lock rotation switch has been removed from this version of the mini. I actually found it really convenient to use on the older Mini's whereas now you have to enable and disable it through the OS like you would on the iPhone. Not enough to dock a point for but something worth mentioning.

I've always been loyal to Kindle Fire and if they worked well consistently they'd still be my first choice, but the 2014 fire 8.9 hdx that I have freezes constantly -- I have to do a hard re-start at least 4 time a day, so I decided to try this tablet (I have an Ipad Mini 2, but it is way too slow and I often have to hit links 2 or 3 times before they work when online, which aggravates my neck and wrist problems and is just annoying). This tablet is much better than the Mini 2, and for me, better than the Ipad Air 2 (the larger size caused problems with my wrists when holding it). There are a few annoying things about this tablet (no tablet is perfect) like no back button and missing some of the android apps I use a lot and I'm very disappointed they used a slower processor than the one in the Air 2, but overall it is a great tablet (and I've never been an Apple person). I did have to spend more money than I would have liked purchasing necessary apps because all my apps are for android (and most of the time the Apple apps are much more expensive than their android counterparts. For example one app that I use daily is $3.99 at Google Play and Amazon and it's been offered several times as a free app of the day by Amazon, but through itunes it was $9.99, which I think is ridiculous and was one of the reasons I avoided Apple products for so long), but even with all that I would highly recommend this tablet. 4 | R13GTXLOJQ7YFL 5.0 Best iPad mini Yet 10 13 I've really liked the iPad mini from the start but in the beginning they were filled with old parts and the speed and capabilities left a good deal to be desired.

The installation was a nightmare 2 2 Ok, the iPad is awesome. The installation was a nightmare. It got stuck on a "slide to update" window. I had to use old computer to google this glitch in installation which is apparently very common with iOS 9. I had to connect with cable to PC, download iTunes and iCloud then upgrade the iPad via iTunes and the PC before it worked. It took close to three hours to install due to this glitch. Now it works perfectly. 8 | R3W4EPNHKXPW4Y 5.0 great! 2 2 this is by far the best screen resolution i have seen in awhile. it beats the ipad mini 3. fast. clean. beautiful. it works the same as any other ipad so not much more i can think to add. now about the price here. this should retail (msrp) 599.99 for a 128gb with wifi only. don't be taken by those trying to sell it for more. 9 | R3BXV197Z22H4B 5.0 New ipad 2 2 Love my new iPad mini!

Hopefully, it will work normal. 11 | RNGN5XEP4UUHW 5.0 No tablet like Apple iPad Mini 4 1 1 No tablet like Apple iPad Mini 4, this one is fast, small and the retina screen just plain rocks. i love it. 12 | R1P9T467ATI5MX 5.0 Unbeatable quality and value 0 0 Quality is top of the line. And it's built rock-solid. Well worth the money, because it should last for years, aging gracefully. And, as with most Apple products, it's ridiculously easy to use.

With my prime membership, I was supposed to receive it on Monday nov 2. I did not get it till Wednesday nov 4. It's not that big of a deal, but I've never experienced this kind of delay before (especially with my prime account). As for the case, the magnets aren't as strong as I thought they would be. The case is pretty and nice, but I wish the magnets were stronger. It's a decent case and protects my iPad mini 4 pretty well. I just hope it will hold up over a long period of time. 23 | -------------------------------------------------------------------------------- /data/reviews/B0178NQOM4.txt: -------------------------------------------------------------------------------- 1 | R3U4B7N3HQIQD4 5.0 The New Standard in Budget Tablets 27 33  Read before watching: This is my 4th budget 7inch tablet. These tablets fall into the budget tablet category. The tablets that i'm comparing the NeuTab against are priced $65 or less. What stands out the most is the viewing angles on the IPS screen. They are absolutely stellar. I use these tablets as digital photo frames and Spotify remotes. Just two strips of velcro will get them to stick almost anywhere. In my video the NeuTab is the leftmost tablet. It's clear that the angles are drastically different. I love these as connected photo frames and the expanded viewing angle really makes images pop. Android 5.0 is slick. The interface is revamped and cleaned up. I review lots of items on Amazon and as a result companies send me their products to review. Generally this means that I have the opportunity to test more of a specific product than the Average consumer. I've owned and tested over 15 tablets so please understand two things: 1) I have tested much of the competition. This means I can answer questions for you. 2) I received this product in exchange for this review. I don't need another tablet so please don't assume that i'm writing a positive review just to get the product. I don't take the time out of my day for that. The video shows the NeuTab viewing angles compared to similarly priced tablets. I will continue to test this tablet and if any issues arise I will be sure to report them. I also typically respond to questions within 48 hours so please feel free to ask questions below. Update 11/3: Preloaded apps: Before I get into what's preloaded, the benefit is in what ISN'T. A lot of budget tablets come with "explorer", a web-browser that never sat well with me. Other tablets also are blatantly rooted with random apps that I always try to delete. Installed List: Android Stock: Calculator, Calendar, Camera, Chrome, Clock, Contacts, Gmail, Google Play, Google Settings, Maps, Photos, Play Music, Play Store, Voice Search, YouTube Other: Downloads, Settings, Sound recorder, ES File Explorer Thank you for reading! 2 | R1FQYDWVWRWH5Y 5.0 Replacement for my outdated Kindle Fire...I like the NeuTab better! 12 15 I've had an original Kindle Fire for a few years now, but felt it was time to replace it. Mainly I wanted something for reading comic books on Marvel Unlimited (which the Kindle Fire cannot do), and for general web browsing / YouTube. I don't play games so I can't say whether or not specific games will or won't work on here. I just wanted something for casual use. With that said, I absolutely LOVE this tablet! Best bang for the buck, by far. I actually like it 100 times better than my old Kindle. The screen size is roughly the same (the NeuTab screen may be just a smidge...1/8 of an inch at the most...narrower than the Fire). Its much lighter weight. The Kindle Fire weighed nearly a pound, while the NeuTab weights approximatley 9 ounces. So its much more comfortable laying in bed and reading on here without my wrists getting cramped. I like the fact it has a mini SD Card slot, and you can charge the device using either the DC port or a standard USB adapter like you use for your cell phone or other devices. I actually prefer charging through the USB port, but the DC port works fine as well. I really have no complaints about this product. If anything, I would add a suggestion...I'd like to see an LED light of some sort to show when new Facebook messages come in, or to tell me when my device is charging. If you have $200 to blow on a toy, then maybe you should look at a Samsung. But if you're like me living from paycheck to paycheck and just need a casual device for web browsing and reading, this NeuTab is perfect. I'd gladly buy another NeuTab product in a heartbeat. 3 | R3FT713BUEZ3I1 5.0 Basic and FAST 16 21  HD version of video on YouTube, search for: Kilgore NeuTab N7s Link to HD version on YouTube is in the first comment for this review. Tablets keep getting both cheaper and better and this is a great example of exactly that. My favorite feature is that there is a dedicated power port which means you can plug a flash drive with media into the micro-USB port and still be able to run this tethered without using the battery. Some other budget tablets use a single micro-USB port for both power/charging AND data exchange. The speed of this tablet is very noticeable. I bought a similar sized unit from a different company two years ago, and the delays for loading apps and accessing network information was palpable. The video shows real time use of YouTube and Google Maps with Street View. In both cases you're seeing these without any cached information. The only speed issue you should consider is that it does take about 40 seconds to boot up, which isn't atypical. The speaker is nothing to brag about, again, that's typical. I had no problem connecting with a set of Bluetooth headphones which is probably what I'd recommend. The screen is IPS which appears to be pretty standard now. What this means is you get an outstanding flexibility to view at almost any angle. Note that this does not have GPS installed. Also, the cameras are serviceable, again, typical for this class of budget unit. HIGHLY recommended as a basic utility tablet. Nice small footprint for travel and vacation. NeuTab puts out a small line of tablets with minor variations between them. This one is their smallest and lightest (9 ounces!). I really like the fact that they don't include any bloatware. I get VERY annoyed at having to get rid of unwanted apps (and they don't always go away). Manufacturer sent me a test unit for review, no other remuneration, no review requirements. 4 | R18F0SCHNMRV7Y 2.0 Suggested for People Who Are Not Tablet Users 2 2 I received this table in the mail, for the price, it certainly is not that bad. If you read books with apps and only want to then this app is perfect, it's clear enough to read books and looks great on the screen size. First the brightness beware, you can literally turn this screen to jet black which is odd so do not turn it all the way down. The screen will began to flash when you plug it in if you do so. The battery is built in, you can not take apart the back, so if the battery goes bad , you can't fix it. That being said I personally did not like this device. The tablet I ordered began to flash orange and red lines when I watched videos on it for long periods of time. Display: The display has a grayish screen tint to it which makes you feel like you can peel back the casing to expose a brighter screen. I've even used some Chinese phones (I own one now) with great displays that could put flagships devices to shame. I would compare the screen to a the first generation 2012 smartphone. When the screen is tipped back the color does not go inverse which is a pro so you can view it from any angle. You can see the dots in the icons and you will see a few jagged edges and if looking at gradient coloring (looks like 2005 internet graphics), you will see the colors do not blend smoothly. Speed: I played Does Not Commute and used the internet to browse pages and it didn't freeze at all. It is slightly slow on the internet. You can run about six apps at once without noticing a lag. I had mainly language learning apps Dualingo and heavy messengers like Line running. If watching a movie, you will notice the lack of quality in the display screen. Keyboard lags a bit when typing and is not fast, you will have to clear the RAM a lot. When watching a movie, you will notice a slight lag to it. Sound: Is not as bad as everyone makes it. It sounds a little tinny which is expected but you can still listen to a few good classical songs and hear the music. If you are not expecting a giant speaker to blare music from and use headphones, then this works. Camera: quality is awful, imagine 2nd generation web cameras. It gets the job done, this is perfectly for people who want to watch a Youtube video here and there, want to look up something on the internet and then use a few messaging apps, maybe play a few light games and maybe even one heavier game. Not for people who are used to retina displays, using Samsung or used to looking at bright colors or high resolution screens. 2.5/5.0 5 | REM465Y0Q9M13 4.0 I am a housewife and a mom on a budget.. 3 3 I was looking for a tablet i can easly take with me to shopping ,traveling and reading books. I am happy with the purchase since I am on a budget and look for the best think I can get and last long for me to say it was worth buying. I only have it for a day and will see how I will lime it. 6 | R2U32ST0D15SYT 5.0 More than Expected 2 2 Well, I expected to receive a very limited, basic tablet at the selling price. Boy, was I surprised. Far exceeds my expectations. I would recommend the tablet to anyone. Full of features, well made, easy to use. The Neutab N&S Pro 7 Inch unit is great. Only negative was not enough volume --- but I have a current hearing issue (my fault). Don't hesitate to order one. 7 | RX9HOCT7M0M0P 5.0 Excellent budget tab@cheap price 1 1 I bought this tab for my daughter.This is having more features.It has a mini SD Card slot, and you can charge the device using either the DC port or a standard USB adapter like you use for your cell phone or other devices. I actually prefer charging through the USB port, but the DC port works fine as well.this option wont available in other tablets. I really have no complaints about this product. I would like to add a suggestion...I'd like to see an LED light of some sort to show to tell me when my device is charging. Camara piture quality need to be improved,I have actually Samsung and apple tabls.I bought this just for my daughter and once i saw the feature , I'd gladly buy another NeuTab product in a heartbeat.I have suggested my all friends this tab.They are also willing to by this product soo.Thanks@Neutab. 8 | R3QGCOERREY8GY 5.0 Awesome 1 1 For 50 dollars this tablet is amazing! I've been using it a few days for games, movies and Web surfing. It is very fast and smooth operation. Haven't noticed any lag. Completely recommend it for someone looking for a table to game on, watch movies and surf the Web. One thing I couldn't find was a task killer on it. It does come with one but you have to install it. Go to apps and click on es file explorer. There is a es task manager that you can install and it works great. The battery could last longer but for 50 bux can not complain. Also I had to set the time zone when I got it. If you looking for a tablet for your kids it's great for games and for the things I use it for works great very happy =) thinking about getting another for my husband that keeps using it 9 | R3V9YHQGUO0FPG 5.0 Good device for a good deal. 1 1 Everything I expected about this product was delivered when I got my hands on this tablet. The screen is as advertised, the thinness and portability and small size is exactly what I wanted, so I can carry it anywhere especially since I'm a student it is ideal. The app store and OS works the way I've come to expect with many other quality android devices (like my LG Optimus phone) and it is very satisfying. And for its budget price, it is a great deal. 10 | R18MOQPCA6OMVY 3.0 Decent tablet upon first inspection. 3 4 Decent tablet upon first inspection. Nice looking screen and decent specifications for the price. Shortly after using the unit, it froze up and the battery became very warm. It had to be hard shut down and reset to factory settings before it was usable again. Once the unit was finally back up and running, the screen was not very responsive and the unit had a lot of lag. Not confident in the longevity of this tab. Sadly, I'm returning my unit. 11 | R2A4GP6HCN210H 5.0 web browsing is easy, and I love the book reading feature not ... 1 1 I found this tablet to be everything that I need in a tablet, bright screen and touch sensitive touch screen. I have owned a 7" tablet before but this one surpasses my previous one in every function, web browsing is easy, and I love the book reading feature not to mention that I love the fact that Google play store was already added to this tablet....well worth the money, I am completely satisfied. 12 | RBOWC713Q4DDS 5.0 Needed an Android device, this is perfect 1 1 I ordered this because I needed a low cost Android compatible device. I have a Kindle Fire HDX and Windows phone but neither are Android. Was really impressed with what I got for the cost. Does everything I need and has become my favorite go-to device. Quick shipping, I use this device for traveling, came with screen protector, charger and com cable. 13 | R3TMBS02X63J66 1.0 NOT happy 1 1 It forced me out of almost all apps I run, even facebook.I did a reset as instructed to clear caches. It indeed works a little better after that, but I can't keep resetting, then keep downloading all my apps. Too many troubles, not happy 14 | RKA3EURKBHLWB 5.0 Great little tablet with a very clear picture and fast ... 1 1 Great little tablet with a very clear picture and fast response times. It is very user friendly and light weight. Wonderful product and I love that it has the google playstore app already on the home page. 15 | RV1JDAC0M5O7R 2.0 Two Stars 1 1 Ordered four, two came dead on arrival. There is a note in the packing - if one writes a good review gets a little bribe -a protection sleeve. So you may wonder if the good reviews are really genuine. 16 | R2ALQ3S8XPQYLS 5.0 Great tablet for the price glad I can save my ... 1 1 Great tablet for the price glad I can save my phone battery and put all my apps on my tablet. Just overall great 17 | R1LP5UDXOMJKYY 5.0 Worth twice the price, get it quick before they catch on! 0 0 I am very satisfied with the quality and price of this excellent little tablet. I find the features and ease of operation to be outstanding. I did not expect such a quality tablet at this price point, however, I was wrong. The screen resolution combined with the wifi and Bluetooth features makes this one of my best purchases. I can now access Google Apps without having to sideload them on my Kindle Fire HDX tablet, The tablet comes loaded with some useful Apps, such as Netflix, YouTube and Google play store. I streamed Netflix videos and encountered no lag and I surfed the web seamlessly. I highly recommend this tablet. 18 | R3ME889J7CWZ95 5.0 Nice performance and features at a low cost 5 8 PROs + Quad-core processor: I found the interface on this tablet to be surprisingly smooth. While the tablet does pack a quad-core processor, it is not top-of-the-line. However, I found general web surfing and app loading to be surprisingly good. Some games do run choppier than they would on other tablets, but the Subway Surfers game showed in my video performed very well. For those interested, the GeekBench multicore score came in at 847. + Android 5.1: This tablet comes with Android's latest Lollipop 5.1 operating system, which helps contributes to the tablet's good performance. + Storage: This tablet comes with 8GB of storage. If that's not enough space, you can expand the storage with inexpensive Micro SD cards, like the ones you would use in your phone and some digital cameras. The slot is located on the back of the unit. + 1 GB of RAM: Many tablets at this price point only have 512MB of RAM, so I'm happy to see that this tablet has double the amount. This helps speed up web page loading and switching between applications. + Display: I'm impressed that a tablet at this price point comes with an IPS display (meaning, it is viewable at an angle). The screen is also very colorful and has a decent 1024x600 resolution for web browsing and many games. It doesn't have a Retina resolution, but it is widescreen and works fine for watching Netflix and YouTube. + Two cameras: I couldn't locate the specs of the cameras, but there is a camera on both the front and the back. Low light performance is not great. I wouldn't depend on taking stellar photos or videos with the cameras, but it's nice to have the option to grab a quick snapshot or perform a video call. + Compact size: There is not a lot of bulk with this tablet, which makes it very portable if you're always on the go. + Bluetooth: Bluetooth is also included in this tablet, allowing you to pair it to devices such as a Bluetooth speaker for Pandora streaming, for example. CONs - GeekBench score: The GeekBench score is on the low side, so complex web pages and games may take more time to load or performance may be slow. However, for basic gaming, web browsing, social media apps, etc, this tablet works fine. - Camera quality: The performance of the cameras in low light is poor, and can make indoor video calls problematic. - Build quality: The plastic casing feels a little cheap and not very durable, but then again, this is a budget tablet. Overall, I'm impressed by the performance of this unit given its low price tag. While it's not as powerful as many other tablets, it is great for kids to play basic games or for adults who want to browse the web and read e-books. * A free review sample was provided to me, and I strive to provide an unbiased and useful review to help you make an informed decision. 19 | R3HIY9VF5IF68T 1.0 Keep shopping. 0 0 Returning it today. After several days couldn't get connected to Wi-Fi and impossible to reach customer support -- that being one of the described features in the product description and a major selling point. Online manual offered no assistance on any level, this coming from a reasonably techy person. This was a gift and it flopped. Very disappointing. 20 | R1EZHWL9MH2FKL 5.0 Cute little tablet 0 0 Great little tablet, fits in my hand easily, though smaller in size than I expected.

Save some other unlucky people from buying it. at this point, I would not trust any Neutab product, or their employees. First one I got wouldn't power up or charge at all. I contacted the company. They sent a "new" replacement. It seemed suspiciously like it was not new, and, while it did power up, it also didn't work. 36 | R1LKAREF8DM756 5.0 this tablet is very nice 0 0 I use it to watch youtube videos and I do not have any concerns 37 | RTS9X6Z2QF2YK 5.0 they love it 0 0 I got two for kids.

Had the trouble of backing it up and reformat it in FAT32 but it still doesnt work. Reformated it back to NTFS. Otherwise its a great tablet with many functions I didnt have on my Surface RT. Takes a little while to learn how to do things in ANDROID 2 | R2HNP81VG3XQKY 2.0 Nice Concept, Far from Perfect. 2 7 I recently purchase this tablet and decided to return it. The display was nice, very nice. The screen eye sensor didn't work very well and the screen sleep mode kept activating. The reviews and stats claimed this device to have all sorts of processing power but I have to say it was VERY laggy. Even swiping between screens there was noticeable lag. This was with no programs running in the background. Sound from the device was nice. The value just didn't add up for me. For the money, this should have been a more polished offering from Samsung... Battery life was pretty good but nothing a high level tablet shouldn't have... 3 | R14TGSRJ4IHWBI 4.0 Love it. 1 5 I already had a Galaxy Note 10.1 2014. I passed it down to my wife and bought the Note Pro 12.2. The note Pro doesn't work with Smart View or Watch On correctly. Maybe there will be updates later. Overall I love it so far. This is the sweet spot as far as screen size. 4 | R275LW77O0LS6X 4.0 Super screen, heavy, no Flash 1 5 This has a great screen but it is heavy and has no Adobe Flash which means most Internet videos won't play. Also it has "swipe text" that cannot be disabled that often messes up what I'm typing. Apple has better text corrections. 5 | R2E1C2JGO0TDY0 3.0 Can't watch amazon prime 1 5 Excellent but I can't watch amazon prime on it says device not supported other wise is great....
