Logitech UltraX Optical mouse USB Type-A + PS/2 400 DPI

Exceptional design and Productivity
The stylish curves of the contrasting top panel and black base provide exceptional comfort and hand support in a design that complements contemporary systems. 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.

Long-Lived Productivity
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.
