The first time I thought the keyboard just does not work properly hang the keys or similar. So returned and also get replacement. But again the same problem. I think that the radio of Tastaurtur bothered with something else, possibly. With the phone For this I know myself but too little to adjust because what else. Otherwise, I found the keyboard is not bad, it is small and slim the keystroke well. The key arrangement, however, getting used to, because it is so small, you have almost all the buttons arranged close to each other, the arrow keys are for. B. mounted funny. All in all though not a bad keyboard, but has simply not work for me. The mouse ran without problems, however. Now I have a wired keyboard and a wireless mouse - better alternative because so everything works fine and the cable of the keyboard does not bother me.
