Well I have the Logitech MX1000 and the reciever is opposite the mouse(on the other side of the monitor) and it works fine. In games this puppy is awesome, never misses a beat. Logitech says its the equivilant of a USB corded mouse and I agree. Also the battery lasts for like 20 days on 1 charge and a 10 min charge is enough to last you the entire day.
