The key is poor and there is poor contact which we have to "play" with that it remains connected ... no luck, my home, it disconnects all the time, to the point I can not even type a single letter. In addition, the keyboard consumes too much battery (I have to change every 15 days). The housing for storing the key is not great either, the key can easily fall. Ensured headlock is the point where it is no longer usable ... I can not even return (purchased there over a month).
