I just wanted to let you know I've been using your Evolution trackball for two weeks now, and I love it! As the Webmaster for the College of Engineering at Northern Illinois University, I use a computer for over 10 hours a day. I've used cheaper trackballs and mice and will never use them again. All the pain in my wrist is gone and I feel great now. Thank you for such a quality product.
