After my Nexus 7 had died, I started searching for a new tablet and was having problems finding anything at a good price in the size I wanted. Finally, Amazon announced the Fire HD 8 update and given the price I decided to order one, but this tablet has taught me that you do get what you pay for.
This is a decent tablet for the price, but it has some serious drawbacks. The app store that comes with the device is very limited and is missing many apps you would expect to find, for example there really isn't a decent email app in the Amazon app store. You can sideload apps but this is a small security risk, and your results will vary depending on the app. The screen is my biggest issue with the device as it is a much lower resolution screen than other tablets I am used to. Battery life has been decent but not as good as I was expecting. The feel of the device in the hand is very plastic; you know that you are holding an inexpensive tablet.
Overall if you need a cheap tablet, this is a decent choice, but I would recommend saving up for something that has a better screen.
