• Reduce sticking and constant cleaning with optical tracking - a system that works through light with less moving parts for greater durability than ball-based mice
• Users benefit from a smooth, contoured shape that fits both hands - and a wheel that functions as a third button
• The optical sensor within the HP USB optical scroll mouse employs a scan rate of 800dpi and enables crisp motion without a mouse pad, ball or roller
• Left-handed or right-handed users can enjoy a contoured shape that suits either preference

The HP USB optical mouse utilizes the latest optical sensing technology, recording precise motion over a variety of surfaces without a mouse pad.
