  Duration of ownership: 1 Years

  Strengths: Huge ball, optical

  Weaknesses:Drivers, customer support, price, wheel is noisy and cheap, dust on rollers

  Overall Evaluation: At least at a first sight it seems this is a very nice piece of equipment: the trackball is huge and lets your fingers move the cursor quite easily, it's optical, and has four buttons plus a wheel. This is why I bought it, but boy was I wrong. Drivers are just dodgy, they mostly work but they have huge conflicts with a lot of software and particularly with dotNET. After asking to the customer support 5 times about it I actually got a reply: we know it and we don't have any plans to fix it (and it's nowhere to be seen in the faq or troubleshooting). Another huge problem is in fact customer support: you get automated, non-related response most of the times, if you're like to get a reply. Sometimes emails bounce and a couple of replies had a link which didn't work.Continuing with problems: the wheel feels cheap, is very noisy and recently doesn't work well anymore. For a product that costs well more than 100? this is ridiculous. Price is in fact about twice of what should be (it's basically a big optical mouse upside down, no frills) and it's not even cordless.Some minor annoyances are the fact that the tiny cylinders get very dirty very fast and have to be cleaned almost every day.But I think the thing that enrages me most is the customer support: for that price you get basically ignored and it feels really bad.

  Strengths: The ball works

  Weaknesses:The programable keys do not work.

  Overall Evaluation: The Kensington Expert mouse is no longer supported in Vista and Kensington confirms no additional support. The track ball functions and the left and right buttons work but the remaining buttons are not functional. None of the button keys are programable and there are no software updates planned at this time.

  Duration of ownership: 1 Days

  Strengths: large ball and buttons make use easy. My hand and fingers don't get cramped since it can be used in different positions

  Weaknesses:Scroll wheel is cheap and sticky feeling (may change when broken in?) but that's not so important to me anyway. The PS2 adapter was not in the box.

  Overall Evaluation: The main reason I bought it is to relieve the wrist and finger pain I had from every other mouse and trackball, which it does well. It's easy to switch hand and finger positions to keep them moving.

  Duration of ownership: 7 Days

  Strengths: Nice Hardware

  Weaknesses:Cannot change settings under Windows Vista

  Overall Evaluation: This trackball is a huge disappointment with Windows Vista. Every time I log on, I have to change the mouse settings; the settings are not saved when I log off. The buttons are not programmable under Vista. I had an older version of the Expert Mouse that I used with a Windows 95 product and I loved it. Unfortunately, this version offers few of the advantages of the original product. Kensington Support has not been helpful. If you use Vista, look elsewhere.

  Duration of ownership:

  Strengths: Optical, from Kensington, good customization, better than Logitech, large ball.

  Weaknesses:Minor dust buildup creates major dysfunction.A step backward to the inferior Logitech types.

  Overall Evaluation: Compared to the older Expert Mouse Pro with real ball bearings this one is feels flimsy. The ball is not as heavy as the Pro. My number one gripe is that the little beads the ball rest on get sticky from a buildup of microdust and palm oils. This requires constant cleaning. The Pro model uses 608z bearings and is immune to microdust buildup. If you are not going to pay out for the Expert Mouse Pro you may as well buy from Logitech.
