the sound is very nice, in someways limited, pictures come out crisp and clear, easy to change with zoom. It is able to read .txt documents and even has a scroll fuction.. The major complaint that it can be difficult to move thru files. Not enough room for the finger to slide thru files, keeps selecting files you want to skip.
Even in bright sunshine you can still see some of the screen, not great but better than most cell phones.
returned due to buzzing sound..........
The screen is very responsive and we have no problems with selecting the desired icon. My daughter loves it very easy to use and high quality.
for the money this is a good item
