The Kensington Expert Trackball Mouse

Here is a good 1 minute video about the Kensington Expert Wireless Trackball Mouse. These work great if you just want to use your fingers to control your mouse and not have to move your arm. They also of course work well for people who have trouble moving their arm. Using a trackball does take a little getting use to and the sensitivity can be adjusted in the mouse settings on the computer. These normally sell for about $150 at Bestbuy or on Amazon.
