Summary: The best. Cured my wrist pain.
Comment: 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.

Summary: not fully supported in Vista
Comment: Thank you for contacting Kensington Technical Support.
We regret to inform you that, our Kensington mice are compatible with vista as a normal mouse but it will not give the capability of programming the buttons.
There will be no Kensington Mouse Work's software support on windows Vista and there is no way to program the extra buttons of the mouse or trackball in Windows Vista.
We apologize for any inconvenience this may have caused to you.

Summary: Love the functional capability, but...
Comment: Love the funcitional capability of this mouse, but the angle of the mouse puts my wrist lower than my knockles and this hand position causes irritation to my wrist. The wrist support that ships with the device cuts into my thumb and does not provide the needed support for extended use of the mouse. As a result, I am still in need of an ergonomically designed mouse that is high function and friendly to the wrist, and am currently searching for one.

Summary: Excellent
Comment: This is my third one purchased, excellent product. This is the only large trackball out there available in this price range. I've used mice, trackpads, pointers, etc. nothing works better for me. I just wish someone would come out with something similar or better...

Summary: Does not play well with Leopard
Comment: Having owned and enjoyed a prior incarnation of a Kensington trackball when running OS9 on an older computer and in spite of some reviews on the Amazon site warning of problems using a Kensington device with OSX, I eagerly anticipated the arrival of my Kensington Expert trackball only to be bitterly disappointed. Even after downloading updated software, it is still "clunky", ergonomically clumsy and much less sensitive than the plain old Apple Supermouse which came with my computer and which can also scroll laterally. The buttons do not fall easily under hand and it does not respond well to OSX type commands. My only regret is that I was so sure that this was going to be a success, I did not save the packaging so that I cannot return it to Amazon. Save your money.
