The keyboard makes a very stable impression and writing is very pleasant. Unfortunately, it happens to me very frequently, that appears twice in one touch the letter. Unfortunately I have never found a way to adjust the sensitivity. Even a change in position of the radio receiver has brought nothing. The included software is unfortunately only very modest. It has eg no way to replace the mouse key assignment for left-handed (I had in the meantime used for battered right hand) and if you 4 actually user-definable function keys are assigned differently (eg browser button Sound mute), then it works best only when second or third attempt. However, since the main purpose is the (many) writing and works very pleasantly, I'll keep them.
