as one of the comments here at the beginning everything is fine, but the first keyboard was broken quickly, the battery which is reloaded after a rap more ... change "finally happy and effective idea of the result, problem today the keyboard starts to do anything again, type letters in rab, etc, in short unusable AGAIN! So I will still return the once amazon and we'll see for the rest .. otherwise I would just like to clarify at the keyboard no diode for the shift key .. so if you want to fully support the top and then you want to type a password for example not surprising that it does not stick!
