This
high-performance trackball optical mouse offers a contoured
shape and ambidextrous design for improved comfort for

control: just a slight touch on the trackball lets you
control the cursor with superior speed and accuracy.
Patented Marble® optical technology offers enhanced
precision, ensuring faster response and smooth, reliable
tracking. The larger size of the trackball improves control
while reducing hand and wrist motion. Four customizable
