Input: I developed wrist problems using a regular mouse for so many years that I needed a change. This trackball is great because it requires no side to side movement of my wrist. <br /> <br />I use only my index finger to move ball around and click using my thumb. The movement is so smooth and accurate unlike a mouse that \\"snags\\" sometimes. It also used less desk space because it just stays in one position.   <br /> <br />I will never go back to a normal mouse again. <br /> <br />
