A large
sturdy trackerball. A full-sized, three button trackerball, which
is 100% Microsoft mouse compatible. Just plug into the PS2 or USB
port on your computer and you are ready to go.
The
low profile case acts as a natural hand rest and minimizes the wrist
angle by mirroring the natural contour of the hand.
Includes
a "drag lock" feature - simply press the drag button and
the button stays 'locked' until you press a second time.
Supplied
with PS2 connector or USB connector. For PC only.
