By replacing the ball and all moving parts that were previously necessary for movement, the mouse becomes more durable and precise than a conventional ball mouse. No more unpredictable mouse movements. The optical sensor transmits 800 signals per second to the digital signal processor, preventing unwanted jumps that can regularly occur with ball mice. No cleaning required. The reduction of moving parts results in minimal dirt accumulation, making the optical mouse virtually maintenance-free. No mouse pad needed. The mouse is so precise that it can be used on almost any smooth surface. Easy side navigation. The scroll wheel allows you to effortlessly browse through documents and the World Wide Web.
