Unfortunately, the radio transmission works strange When booting from the BIOS keyboard and mouse will be immediately recognized by USB. When booting Windows I come up to enter the password. But as happens only once nothing, react neither keyboard nor the mouse pointer. Only when Windows is fully loaded in the background, I can finally enter the password and the mouse works. The mouse is actually very small, smaller than usual, so I can work with only very uncomfortable with my somewhat larger hands. It is ideal for children.
