Our Analysis

While most users today prefer a mouse, other pointing devices, such as the Kensington Expert Mouse optical USB trackball, still are favored by some. One reason is that experts say that they are less likely to cause repetitive stress injuries. Although the Kensington Expert Mouse scores fairly well with users and reviewers, most instead give a slight nod to a different trackball, the Logitech Cordless TrackMan Optical (*Est. $50).

We found lots of reviews of the Kensington Expert Mouse optical USB trackball. Because the trackball has been available for a while, however, many of the reviews are dated and most are not comparative. The most current professional review comes from an unlikely source -- CounsellingResource.com, a website devoted to mental health -- where the Kensington Expert Mouse is evaluated as a way to reduce repetitive stress injuries. The high quantity of user reviews at Amazon.com makes this site an excellent source for buying guidance on the Kensington trackball mouse.

The Kensington Expert Mouse has a large number of customer reviews at Amazon.com, which collectively give a great overview of how users rate it.

2. CounsellingResource.com

This website is devoted to mental health, but Dr. Mulhauser reviews the Kensington Expert Mouse Wireless as an option to prevent repetitive stress injuries. One advantage of the Kensington trackball is that multiple buttons reduce the need to shift between the mouse and the keyboard. While Dr. Mulhauser likes the Kensington Expert Mouse, in a later review he says he prefers the Logitech TrackMan.

4. R4NT.com

Reviewer "D4V" mentions previously reviewing a Logitech trackball, but makes no comparisons with the Kensington Expert Mouse. The reviewer notes that it takes some time to get used to using a trackball and that the original one had to be replaced after one week because of frequent lockups. Still, the Kensington Expert Mouse is recommended.
