IOGEAR new Wireless Laser Mouse is an excellent tool for medical offices, libraries, and schools as well as for mobile professionals, gamers, and desktop users. This new IOGEAR mouse uses VCSEL (Vertical Cavity Surface Emitting Laser) as the light source, which provides 28x more tracking power than mice using an optical sensor. VCSEL allows the mouse to work on virtually any surface, even glass, and provides an extremely high resolution of 1600dpi, substantially reducing the amount of injury-producing hand and arm movement. IOGEAR Wireless Laser Mouse is USB ready, Plug-n-Play, and Hot Pluggable. It provides a 6 feet (2 meter) wireless range, and it is also backed by IOGEARs 3 Year Limited Warranty.
