From the comfortable shape to the precision scroll wheel, Logitech Pilot Wheel Mouse says Logitech quality, but at a value price. Setup couldn't be easier - just plug it into the PS/2 port and the mouse is up and running. Pick it up and notice how it fits comfortably into your hand. The keys are subtly shaped to provide a natural place to rest your fingers, while the sides are indented to make the mouse easy to hold and lift. Scrolling documents and web pages is a breeze too, thanks to the smooth and precise scroll wheel.
