Kensington Expert USB

Although it’s not as big as Logitech, Kensington manufactures some of the best trackball mice on the market, and it’s known for ingenious mice designs, as well. Clearly, the trackball mice aren’t intended for gamers, but there are many laptop users that would find Kensington’s Expert Optical Mouse useful, especially in those places where you can’t really find enough room to operate a classic optical mouse.

Of course, Kensington is boasting a bit saying that this is the best trackball around, but that seems to be the truth if we take a closer look at the Expert Mouse. Designed for PCs and Macs, the new Expert Mouse integrates Kensington's Diamond Eye optical technology for smooth, precise cursor movement.

Surrounding the ball, there’s a brand new implementation of Kensington’s award winning Scroll Ring technology that puts scrolling right at your fingertips, literally. Plus you get 4 customizable buttons around the ring, too. The guys over at Kensington even provide extended ergonomics, including a soft new wrist rest-right. The Expert also provides full USB support.

Here are some more highlights for the Expert Mouse:

• Largest ball of any of the mainstream, consumer devices
• Great momentum and virtually frictionless rotation
• Detachable wrist rest cradles your hand in comfort

Amazon has this one for about $66.24.
