My goal: to listen to music in bed for a little computer 10 'and under W7 with Windows Media Player 10 ... Only one problem, how to change tracks and adjust the volume? I wanted a remote control for a while. It does that very well and the sensor (in the shape of a little mouse and appeared a little cumbersome) has the advantage of capturing the signals regardless of the orientation of the order. Perfect for my use! Small +, you can also turn off the computer. without moving.
