DELL Optical, 2btn, Juoda

The Dell™ USB Mouse is a sleek, intuitive input device which adds new levels of comfort and control to your computing experience. It uses an advanced optical sensor technology that records motion more precisely than a traditional mouse. Ease-of-use and better reliability are assured because there are no moving parts to wear out or collect dirt and dust, so the mouse always stays precise. The optical sensor replaces the need for a mouse ball allowing it to work on more surfaces. No mouse pad is needed to use this device.
