The touchpad, replacing the traditional mouse-wheel, is a step towards enhancing computer mouse capabilities. By gently touching the super-sensitive pad with you finger, you can move the cursor to the required position. The MC-802 mouse can scroll the display up/down/left/right, enabling convenient and smooth navigation through documents, images and spreadsheets. An optical sensor with a 800 DPI lens works very well on almost every surface.
