When the keyboard and Mausset arrived with me, I had to first of all the spacebar again use because they lacked during transport. It was not enough, they simply draufzustecken again because they did not have this right and the left and stability again "aushebelte" if one does not express exactly in the middle. But a wire below the key is found, the set when the button is fixed. The next problem was the USB Nano Receiver, I initially did not find, as he put it in the mouse (at the bottom). This was not explained in the manual, whereas the battery replacement has been carried out on 2 sides. The keyboard itself is quite small, so I did not expect. And the keys are relatively difficult to press. They can not touch only briefly, but must in relation to my previous keyboards already spend more pressure. The mouse is quite good in the hand and does not turn on when using fast to standby mode, so that it is very energy efficient. The layout itself I really like. And after I had installed the program for the radio set, both worked well right away. There has been no interference.
