Overall great trackball, but for me I need to adjust the way to rest my hand.

Summary: I did not see anyone mention that the upper right button is too easy to click accidentally if you rest your hand over the ball and rest your finger near the upper two large button areas. This becomes problematic if you assigned the upper right button to be browser nav forward. This is the default setting if you installed the trackball works software. I had to disable the upper right button so I don't accidentally click the nav forward while I'm on a website.
Excerpt: Love this mouse. Extremely accurate pointer which is essentially when playing with inches. Programmable buttons allow for quick shortcuts whether it's a command or even lock your computer quickly. The sensors can get dirty but it's very easy to clean and have had this for over 2 years without a problem.
Pros: Durable, Easy to Use, Quality, Good Value, Comfortable, compatible, adjustable
Nice idea, best pure trackball, poor buttons, wrong tilt

Summary: As a thirty-year computer professional - and player - I feel qualified to offer the following opinions. General comment - I loathe thumb-operated trackballs (purely personal choice). I don't care for mice. I'm still searching for THE trackball for me - thus far no one has provided the correct combination of features. I have large hands and I want something that both fills the hand and allows my fingers to spread out to prevent cramping.
Excerpt: Digital music composition and editing present special problems. Experts often recommend learning keyboard shortcuts to speed up things. But that requires learning multiple key-strokes. This trackball is superb. It is fast and more important -- extremely accurate. I have used it on Protools, Cubase, and now on Logic Pro X. It's the best -- you'll love it!
Pros: Durable, Easy to Use, Quality, Comfortable, compatible, adjustable

Summary: Quick and easy setup. Just take it out of the box. Plug it in. Download Kensington Trackball Works and you're set. EARLY IMPRESSIONS: Coming from having owned the best of the best mice and trackballs from Logitech such as my current Marble Trackball, the M570 (which possibly contributed me the De Quervane syndrome I have now) and the Anywhere Mouse, not to mention scores of other mice and trackballs over the years include the 1990s version of the Kengington Expert Mouse...
Summary: I have the other version of the trackball the Expert Mouse. This is even better. I love the spinning of the wheel to scroll. My only problem occurs when I go back to my office and start spinning the trackball on the Expert Mouse and no scrolling occurs. (Have to use the ring on the Expert.) I have read reviews complaining about the software but I am not sure I understand the complaints. The software is completely customizable.
The Slimblade really is better than the Expert Mouse Trackball - why did I wait so long?
17 January 2013
Summary: I have used the Kensington Expert Mouse Optical USB Trackball for as long as I can remember, avoiding the Slimblade. After a week's use of the Slimblade, I am sorry I waited to try it. It has a smoother action, the same 4 buttons and the same size ball as the Expert Mouse Trackball. The lower profile causes less carpal tunnel discomfort, and I don't have to use the the dopey detachable wrist rest.
Summary: It's still my favorite track ball design. I've gotten used to the scrolling feature which is now accomplished by turning the trackball like a water faucet. I had the previous version of this track ball that had the scroll ring. So this took a couple of days to get used to it. My biggest disappointment is the software. MouseWorks did so much more.
Good hardware, but here's what their Software Support lacks

Summary: This product almost needs to be reviewed on 2 separate fronts ... the physical hardware (trackball), and the product support. As for the trackball itself, I love it. Great aesthetics, the rolls cleanly and smoothly, the functionality of "Twist to scroll" is a great feature that becomes second nature after just a short time. Easily a 5 star product. However, the deficiency (as you've surely read already) is in the software and driver support.
MS Explorer Trackball users, you'll be ok (AutoCAD user here)

Summary: I have used the MS Explorer Trackball for more than 10 years and absolutely love it. By far, the most comfortable option for a trackball on the market. Unfortunately, they don't make it anymore and mine has finally worn out. In the past, I had used a Kensington trackball and really enjoyed it, but knew it didn't have the same natural hand position that the Explorer had. I decided to give the Slimblade a chance. At first, I was really struggling with the change.
