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.
Summary: I've owned the past three versions of the Expert Mouse, and while there have been incremental improvements there was usually still something that didn't add up (much earlier white versions had adb adapter connectors that tended to have issues, on the previous black and grey version this was the scroll ring - it felt rough and jerky, like plastic rubbing on plastic). Everything about this version of the trackball is better.
Skeptical as I have a Microsoft Trackball Explorer

Summary: Having used the Microsoft Trackball for five years or more and being very happy with it, I needed one for home, but the (idiot) folks offering them at $400+ get by disdain, not my dollars! The Kensington price was scary, so when it dropped to the low 80's I risked it. It is VERY solid, easy to program the top two buttons, great with the horizontal scroll operation and the enormous left and right buttons are so easy to use!
Summary: This is a smooth operating Kensington trackball. Build quality seems up to Kensington standards. I replaced a Kensington expert trackball with the scroll ring. Personally, I don't see that scrolling with the ball is any advance over the ring; in fact, I rather prefer the ring. The profile on the slimblade is, of course, lower, which some may find more comfortable than the expert mouse but, again, I don't see any particular advantage myself.
Disappointed in the slimblade compared to Kensington Turbo Mouse

Summary: I was forced to get a new trackball because my new Mac OS would not operate the old Turbo Mouse software. Primarily, I use my trackball for Photoshop and design work along with regular computing. I was very disappointed to find the slimblade did not have the refinement of the turbo mouse. My turbo mouse was a joy to operate with the trackball resting on 3 stainless steel bearings.
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
David Learned, Amazon
5 November 2012
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.
