Customer Reviews

Great Pruduct
I've been using this trackball for about a month, and love it. I bought it to alleviate RSI and so far, it's working. I've tried it with WindowsXP and Ubuntu Linux 8.10 and it works very well in both. I was a little afraid that it would take a while to adapt form a mouse, but it took no time at all. In fact, after using it for a few hours, I didn't want to use another mouse ever again. The only complaint I have is that the scroll ring (which is a REALLY useful and intuitive feature) feels...well... cheap. That being said, the ring is still quite functional.

Works fine, just like previous models
Just like the Kensington Trackballs sold for the last 15 years, this new model works just fine, albeit, using a new and different technology. Time will tell if it is durable as the 12 year old unit that the new unit has replaced.

The new unit has a scrolling ring. I will need to practice to get used to using it, as one can still scroll using the old method.

The best. Cured my wrist pain.
I'm a programmer and switching to the Expert Mouse cured my wrist pains completely. Previously I was using regular mice which killed my wrists, then a Microsoft Trackball Optical but that just shifted all the stress to my thumb. At this point I swear by the Expert Mouse and wouldn't use anything else. The MouseWorks software does everything I need and the new scroll wheel is brilliant. I just replaced my older Expert Mouse Pro at home so I have one of these at work and at home. Can't recommend this product highly enough.
