Summary: I use both the Expert Mouse with my Windows machine at work, and the Turbo Mouse with my Mac at home. I love them both. I have "wrist issues" after using a computer at work for almost 20 years now, and can no longer use a regular mouse for very long. I love these trackball alternatives.
Pros: could conform a little more to my palm and fingers
Cons: could conform a little more to my palm and fingers
Summary: kensington trackball mouse for computers is so much better than using the conventional mouse; using the thumb on the trackball to navigate the computer screen , I believe, helps to avoid the carpal tunnel injury; i would encourage everyone to use this device rather than the conventional mouse;
Pros: very well built ; ergonomic to prevent carpal tunnel syndrome
