No-hassle optical technology You’ll love the precision and reliability of this optical trackball. For over 5 years Logitech has been using optical technology in its award winning trackball. Because it replaces the mechanical parts of traditional trackball with an optical tracking system, Marble Mouse gives you superior precision and smooth motion, even if the ball gets dirty or scratched. And, Marble Mouse frees you from the chore of having to regularly clean the trackball.
Comfort and control for left and right hands
