Review: Good size trackball; very easy use with either hand - Great trackball. Easy to connect; just plug the dongle in, and it's good to go. Really good size of trackball allows me to use three fingers to navigate precisely with my non-dominant hand. Comfortable to use from the couch too. The buttons click nicely and the scroll wheel works well. It's definitely a little bit pricey, but definitely worth it to be able to rest my injured dominant hand but still be able to enjoy good precision when using my home PC. The ball comes out easily to clean, so I wouldn't want to take this loose in my bag into the office, but that isn't really a consideration for me since I've switched this one out for the Orbit Fusion, which I'll take to work instead.
Review: I absolutely love it! - UPDATE 24 FEB 2011 Here is an update to my original review. I just as keen on this excellent input device as I was a year ago when I bought it. It has been in constant use and it really is imho the best input device I have ever used. I use it for graphics, mostly in Adobe Illustrator for example and there is so much control and it is precise. Equally it can go very quickly across screens so I can get across my two screens easily. I also use it for editing video in Final Cut Pro and here, it is really superb. It's great big trackball makes it very easy to just creep forward and back a frame at a time. I really do think that people may overlook this terrific input device because it is not slick and cool, but it is very much the best possible thing for the job. My only comment that could be negative, but isn't, is that using it exclusively may risk RSI problems with you shoulder. I think this is true of any mouse of this sort. That is why I also use the Contour RollerMouse Free. This I use for scrolling around word processing documents and that kind of thing. ORIGINAL REVIEW MARCH 2010 I bought mine on 30 January so I've had it for six weeks now. I absolutely love it! I do not use it exclusively, I use it in conjunction with a Contour RollerMouse Free. However I use the Kensington Expert Mouse for graphics. I recently just finished doing a lot of editing of a video with Final Cut Express and the Expert Mouse is superb for this kind of thing. Many years ago I used a Kensington trackball, I think in about 1995, and I really like that one, but this is so much better because it has such a large trackball. The negative things about this trackball are that it feels a bit cheap in construction compared with say, a Logitech or Microsoft mouse at this price, however I think it is well constructed nevertheless. It looks rather 70s to me but I don't mind this. In actual use the feel is very good. The scroll wheel bearing surface is noisy in a plasticy way but there is no problem with this in use. From time to time it is a good idea to remove a build up of gunge on the three little ball bearings. I keep an old toothbrush nearby for this purpose. It's also quite good to take the ball out and polish it, perhaps with your shirt :) Any of these small negatives are hugely outweighed by the fact that the level of control over the cursor is superb. That is what an input device like this is for and that is what it does so well. Before I got this I tried the most expensive Logitech mouse, however the software for that on my Mac was a disaster so I had to send it back. IMHO the Kensington Expert Mouse is a far better buy than that more expensive Logitech mouse. The level of control over the cursor is much better. The software for the Kensington Expert Mouse works very well indeed on my Mac. I use it with the default settings and it is fine. The scroll direction can be switched with a menu in the menu bar at the top of the Mac OS screen and this is very handy. If you buy this you will be initially disappointed when you take it out of the packaging. You will think it is a prop from the Star Wars movie. When you first use it you will think it is a bit weird if you have not used a trackball before. You will still be having doubts. After a week of using it you will never want to use a "normal" mouse again!

## Questions & Answers

**Q: Does the scroll ring have notches as it spins, or is it free moving? i’m looking for something to allow precision zoom/pan control in cad.**
A: There are notches on the ring, but it is smooth.  I use this and the other mouse for AutoCAD Electrical 2023 and have to say the other is the better choice.  It is more expensive, but way way more practical when you need to press a mouse button AND move the wheel.  I also tweaked the CAD zoom factor.  I now find any other mouse just does not perform the same way.  I don't know what the part number of the other mouse is (on a different PC), but it is the big square one.  The ball is about the size of a snooker ball and the cursor does not move when you take your hand away.

**Q: Will it work with windows 10?**
A: I don't have the wireless model, mine is wired which is an older model but it does work with windows 10, so I would expect the wireless model you are interested in to work with windows 10 also.

**Q: 20.1 x 15.8 x 8.5 cm is this size accurate?**
A: These sizes are for a wired trackball not the wireless in pictured

**Q: Is this compatible with chromebook**
A: Hi,

Thanks for the query.

There would be no problem at all with using this with a Chromebook. These are ready to use any external mouse when connected. 

Kind Regards,

### ⭐⭐⭐⭐ Good portable trackball, but doesn't quite match my old favorite
*by J***N on 5 September 2025*

After years of faithful service from my Kensington Expert trackball, I decided to upgrade to the SlimBlade Pro for its portability and modern features. While it's undeniably a quality device, I find myself missing some aspects of my old reliable Expert. The SlimBlade Pro's biggest strength is definitely its portability - being able to easily slip it into a laptop bag and use it anywhere is fantastic. The dual connectivity (Bluetooth and wireless) works seamlessly, and switching between devices is effortless. Battery life is excellent, easily lasting weeks of regular use. The twist-to-scroll feature works well once you get used to it, and the clicking sound isn't as annoying as I feared it might be. Build quality feels premium and the device looks sleek on any desk setup. However, for some reason it just doesn't feel as comfortable or natural as my old Expert did. Maybe it's the different button layout, or perhaps the ball response feels slightly different - I can't quite put my finger on it, but something about the overall experience feels less satisfying. The Expert just had this perfect "feel" that I haven't quite recaptured with the SlimBlade Pro. The trackball does pick up dust and grime fairly quickly, requiring weekly cleaning to maintain smooth operation. Not a huge issue, but worth noting. It's a very good trackball that does everything it promises, and the portability factor alone makes it worthwhile for anyone who travels with their setup. Just don't expect it to necessarily feel better than whatever quality trackball you might already be used to. Pros: Excellent portability, dual connectivity, long battery life, premium build Cons: Doesn't quite match the comfort of older Kensington models, collects dust quickly
