HP USB Optical Scroll Mouse QY777AA | Brand new in box 12mth Wty

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 US 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.
