Yahoo Tech: "I haven't been a trackball user for many years, but Kensington's new SlimBlade Trackball could make a convert of me once again.
Foremost this is a standard trackball, but it's one with an impressive feel and immaculate design. The ball is large and rides quite high. At the same time, as the name implies, the base is very slim and flat, the result being that your wrist doesn't strain upwards when you use it and your fingers rest very naturally on the top of the ball when you use it. Buttons are big and easy to reach, too. Overall I found the trackball extremely comfortable even for extended computing sessions."
