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.
Summary: Like many reviewers here, I'm a long-time Kensington "big ball" user. I've tried other trackballs, but nothing has ever topped the big Kensingtons. I've watched this product evolve over 2 decades of being a trackball fan - my first was an ADB (pre-USB for Apple) version. The previous Kensington models -the ones with steel bearings inside - tended to last 3 years or so for me.
Summary: The response is so much smoother and more accurate than a conventional mouse that i will never go back. There is an adjustment period needed if you are switching from a conventional mouse, but once you get used to the way it works, you will agree that this is far superior. You will never run out of mousepad space again! I do a lot of illustrator and photoshop work, and this type of mouse is exactly what i need. I have been using the Expert mouse for years and love it.
Summary: The Slimblade Trackball is a very nice device. I have been using Kensington Trackballs for years because I like that it sits in one place and your fingers intuitively can move a cursor around the screen without moving your hand like with a typical mouse. That said, the Slimblade functions flawlessly, but does not allow the user to program the buttons as on prior trackballs.
Pros: Accurate Tracking, Comfortable Design, Fast Response, Glides Smoothly, Innovative Design, Works On Any Surface
Summary: As a matter of personal preference, I have always preferred a track ball. Trackballs consume less desk space and negate the constant need to move a mouse around. In the case of the Slim blade it functions as advertised (well). Of the trackballs owned previously, this has to be the best. Especially the 2 button that allow use with music or various spread sheets, documents etc. I work with Excel quite often and this feature really appeals to me.
Pros: Accurate Tracking, Comfortable Design, Fast Response, Glides Smoothly, Works On Any Surface
Two button trackball that shoots itself in the foot.

Summary: I've been using Kensington expert mice for a very long time. I've been so pleased with them, I didn't even read any reviews. I just purchased one for me and my wife. Sadly, The top two buttons are useless to me. One does something with one of two applications I never ever use (Windows media and iTunes) The other one does something involving pictures with several applications I don't use, and two web browsers.
Summary: Van alle muizen en trackerballs die ik gehad heb is deze het prettigste in het gebruik. Hij is aan de grote kant, maar dat is juist fijn. De wijze van overschakelen tussen bewegen van de cursor en het scrollen door documenten is even wennen maar werkt wel heel erg prettig. Wel helaas een punt van kritiek: De optionele driver software (Windows 7) werkt niet goed (icoontjes in de systemtray verschijnen meerdere keren (na iedere keer opstarten komen er weer 1 of 2 bij) en...
Pros: Prettig in gebruik (indien driver NIET geinstalleerd)
Cons: Driver software voor Windows 7 werkt niet naar behoren.
