Logitech UltraX Optical Mouse BV-85

Logitech UltraX Optical Mouse BV-85 ... Because this mouse requires less force to grip and control it, it is comfortable for long hours of use. Four programmable buttons, including the scroll wheel, increase efficiency. And, the Logitech Quickswitch button provides one-touch access to open Windows applications directly from the mouse.

State-of-the-art optical sensors provide the smoothest tracking on almost any surface. Since there are no moving parts, optical mice perform without any cleaning or maintenance and outlast traditional ball-base mice.
