All this is quite compact, although nothing is cut in comfort, and both devices are connected by one transceiver, the mouse and keyboard are connected to 1 USB port. The mouse has an on/off switch, the keyboard doesn't. The mouse is powered by 2 AA batteries, the keyboard is powered by 2 AAA. Duracell included. In general - I think it's a good, comfortable, high-quality keyboard for anyone who doesn't purposefully want additions from the keyboard of the kind that it doesn't have and wasn't planned to. And a normal mouse as a bonus.
