Customer Review

on 8 June 2009
Accurate and easy to use. Operate with just one finger or thumb.
As this is an optical trackball, there is no mechanical motion detection mechanism to keep clean to maintain accuracy. (That is the problem I had with it's predecessor.)
Only a very small space is required, near the keyboard. I have used it with my desktop in preference to a mouse (because no space is required on a crowded desk), and with my laptop in preference to the touch pad.
