IOGEAR's USB Optical Mini Mouse 800 is an excellent tool for mobile professionals. The 800 dpi resolution offers twice the accuracy of standard mice, and is ideal for graphics and web designers who demand pinpoint accuracy. It is small, lightweight, consumes virtually no room in laptop carry-bags, works on most surfaces, and needs just inches for accurate movement. The ergonomic contour design offers comfortable use for hours; moreover, its greater speed reduces excessive and potentially harmful arm movement. This Mini Mouse also features a retractable cable that is quick and easy to manage, without the tangles and mess of standard cables. This unit is USB ready, Plug-n-Play, and Hot Pluggable.
