For keyboard:
Application should be in a HTPC. The connection / installation worked perfectly under both Win 7 and Win at 8 / Win 8 Pro.
The keyboard is ansich fine. One can write well and the keystrokes are also fine. What is not at all but acceptable, is the touch surface. The rough surface would not even be a problem if she would react at least better.
Some of clicks are not recognized or not running Mouse movements. At the junction, it is not because keystrokes are transmitted properly. Neither soft brush over yet with a little more pressure does not change. Time goes sometimes not.
The next KO point is the touchpad. It turns seemingly off after a certain time. If you then want to briefly move the mouse must first press any key on the keyboard is mandatory.
All in all the keyboard is unusable so.
As "compensation" I have the Logitech TK820 ordered at so far I could not identify a point of criticism. Yes, it costs a lot more, but it is also worth devinitiv.
