When it comes to a good mouse to use for the computer, the Kensington Expert Mouse Optical USB Trackball is a great choice, whether you are right or left handed. The Kensington Expert Mouse Optical USB Trackball provides more comfort than your standard mouse during extended use because it reduces arm and wrist movements.
The Kensington Expert Mouse Optical USB Trackball features a scroll ring, which allows you to spin the dial to move up and down pages with ease. The Kensington Expert Mouse Optical USB Trackball also includes a detachable wrist rest, which softly cushions the hand and wrist to allow you to spend extended periods of time on the computer, pain-free. Since the wrist rest is detachable, you are able to set it up to perfectly support your hand, regardless of your hand size. This is important when you consider how different your hand’s shape and size is from the people around you.
