UPDATE (16 October 2010): Kensington released their TrackballWorks in June of this year, which release enables users to customize the Slimblade Trackball's four buttons, adjust pointer speed/acceleration/function, and other features. The pointer sensitivity is much improved, though still not as good as the pointer sensitivity module found in the venerable MouseWorks software.

On the other hand, the ability to customize the four buttons of the Slimblade Trackball is a welcome (and much needed) improvement. This device should have shipped with this software.

The advent of programmable buttons places the Slimblade Trackball in a category of its own. It surpasses by a wide margin the ergonomics and aesthetics of the Expert Mouse. The scrolling function is superb, a perfect complement to a trackpad device. I am surprised by how much the Slimblade Trackball just "disappears" while I am working with it.

My only complaint is that the buttons are sometimes too sensitive, something that can be avoided by adjusting how much resting pressure one places on the device's surface.

Those of us looking for an attractive and elegant multifunction pointing device need look no further. The Slimblade Trackball now has software worthy of its stunning good looks.

(The previous version of this review rated the Slimblade Trackball at 2 stars, was found helpful by 190 of 201 people, and was titled "Missed Opportunity".)

(Amazon's system was not properly updating my review, so I deleted and reposted. At the time I did this, only 1 of 4 people found my review helpful. Even so.)

UPDATE (9 March 2009): After 4 days of continuous use. I am packing it in and reverting back to the Expert Mouse.

I've been a trackball user for years and have used several different models. When my last one broke I began researching new models to purchase. I really liked the look of the Kensington Slimblade and from past experiences knew that I liked the feel of a bigger ball. I read a ton of reviews on the product and to paraphrase the majority of them, the hardware was amazing but the software was lacking. This gave me some concerns. However, I looked on the Kensington site and noted that the most recent release of the software was after the posted dates of the review. Kensington must have paid attention to the reviews, listened to their customers, and upgraded their software. After this I decided to make my purchase and I couldn't be more happy. The trackball is a bit pricey, but worth every penny in my opinion.

Personally speaking, there are 3 criteria that make or break a trackball. The first is the amount of friction the ball has against its base. The second is the overall design in regards to comfort and hand movement. And third, is the driver software allowing you to customize your experience.

The Slimblade's friction is perfect. My previous trackball, a Microsoft Trackball Explorer, had too much friction. The ball would stick when initiating movement from a still position. This was very aggravating when I required precise movements like working with a graphics program. The Slimblade never sticks. It glides smoothly and effortlessly all the time. The minimalist amount of pressure will coax the ball to move.

The Slimblade's overall design is sure bliss. The comfort of using it epitomizes ergonomics and the hand movement is practically nothing. I can guide my cursor and click all of the buttons with my fingers without ever moving my wrist.

I bought one of these just after the supporting TrackBall Works software became available which makes the SlimBlade pretty much a superior replacement for the much clunkier Expert mouse. I've used it a few days, but already love the lower/slimmer ergonomics and the all-optical sensing without the roller bearings that can get clogged and stuck. My only nits are the cable and the scrolling. The cable is stiff and covered with a cloth braid that reminds me of model trains made in the 40's. It is wired directly into the trackball case and is not user replaceable. A stand-alone USB cable would have been better. The scrolling mechanism is very cool, but even with the new TrackBall Works software, the right combination of resolution and scroll-rate is not there. The granularity cannot be set fine enough to scroll one row at a time in Excel, yet when set as fine as possible the scrolling is too slow. Scrolling needs to be finer and use acceleration like the X-Y positioning does. Still, this is my 6th or so trackball and it's easily the best.
I bought this unit in early June 2010 and was annoyed to discover just a few days later that it was no longer available directly from Amazon via Amazon Prime. Also, don't be taken in by the third-party 3-year warranty offer: the product comes with a 5 year manufacturer's warranty.
Updated December 2012:
I have had 3 of these for some time and continue to quite happy with them. The ball sits very low to the table and the ability to spin it around the vertical axis provides a feature that conventional mice and trackballs do not have. All 3 have been reliable (unlike the previous generation Expert Mouse which I replaced 3 times (under warranty)). The only negative is that dust eventually blocks the optics, but it's easily removed with a finger and/or by blowing on it.
