I have this keyboard for 6 months already, it works very well and seems to have no problem with the battery (I had doubts on the reliability of the solar sensor). The keyboard itself is very ergonomic and very enjoyable despite its small size, and fully suits me to type my classes. The only big complaint I have to do this is external matter: too soft, very little resistant to shock despite my precautions ...
Overall, a good product I recommend, provided you take care!
