For the money really wonderful and I can only agree with the other positive reviews. Simply connect the mouse and keyboard via one USB and off you go. No installation required, works wonderfully with my 2 Surface Pro with Windows 8.1.
It is at the price of course to unostentatiously decorated goods, the optical mouse (ambidextrous usable) has, for example, only 2 buttons + scroll wheel, the buttons are not illuminated. With the processing, optics and user-friendliness and processing for the money I am more than satisfied.
So if you do not want to spend much money, just what needs to stationary tap in the office and no wireless keyboard, lies right here.
