I read a lot of mixed comments regarding the autonomy of this keyboard, well for my part I find it terrible! Since I ordered I did have recharged only once and yet I use it almost every day. Only negative for me is that the light on the battery does not light, so both or she was flat, I just have not succeeded in connecting the keyboard to the tablet. I have rarely connection failures which have vites resolved by closing and reopening the keyboard. The size is correct to hit, practice keyboard shortcuts and tablet remains constantly touch, which is very convenient. The only downside I could find him is its weight, with the tablet, this is probably as heavy as a netbook, which could be a problem when traveling but you get used very quickly. In conclusion, if I had to buy a keyboard for my tablet, this would be it :)
