Summary: The hand unit is bulky and the left click button is difficult to use when the unit is not resting on a fixed surface. Also the scroll ball wobbles and seems loose in its socket so that it is easy to slide all over the screen of my computer. It does, however, function.
Summary: Overall this product functions well - my gripe is that the battery on the mouse must be charged at all times. It looses its charge within a day if not left charging overnight. but I use it for controlling a pc attached to a 50" plasma so i can sit back and control it.
