The HP 125 Wired Mouse (265A9AA) is an affordable, no-fuss wired mouse for everyday productivity at home, in the office or in the classroom. Its low-profile ambidextrous shape is comfortable in either hand, and the 1,200 DPI optical sensor gives accurate tracking on most desk surfaces. It has three buttons including the scroll-wheel button and connects to any USB Type-A port with plug-and-play setup, drawing its power from the cable so there are no batteries to replace. The 1.8 m cable reaches comfortably from a desktop tower under a desk. The mouse measures 112 x 63 x 36 mm and weighs 80.5 g. This listing is the OEM-packaged version, supplied in plain bulk packaging rather than a retail box, which suits companies and schools rolling out many PCs. HP lists a one-year limited warranty.
