Remote control has a range of ten meters (I have not tested more). How the correct buttons with two functions per button. As against the trackball to the mouse pointer is difficult to use (too sensitive or too loose). It would add a room to stop the ball. The remote is a little fake but this is not very important. Caution plug the dongle into a USB socket very close to the motherboard (so usually not in front) or it is malfunctioning (2 meters worn) Satisfactory.
