Review: The perfect mouse exists and it's this one. - I will legitimately cry when they stop making this trackball. I own two of them -- one for travel and one for my office -- and they're the only thing I'm comfortable using. The efficiency and ease of motion is incomparable for my graphic design work, especially across multiple monitors. Limiting the motion to my fingers has been a miracle for carpal tunnel that had been developing and ended up stopping the development of it altogether. Plus, I often need to work in a very confined space in a dark backstage area where bumping something could be catastrophic, and this keeps my movements minimal in such spaces. It's just perfect, and my oldest one lasted me for 6 years at this point. They're just incomparable products.
Review: 24-hour Initial Review – Early Pros & Concerns - February 04, 2024 Update: Track ball works well. Doesn't seem to have but one issue and that issue is probably my problem. The scroll ring sometimes and my fingers don't jive causing me top hit one of the corner buttons. I must further practice, do much more practice. New Thought, 31dec23: Dragging and dropping, for instance, an email in MS Outlook to a folder can be challenging. I have not figured out the best method. Am looking for any ideas... 28dec23: Overall, I like the trackball and am tentatively at about 60/40 thinking to keep the device. Has many interesting functions and possibilities. Will know more as I work to better use the device. I definitely need more practice with the trackball because my long-term use of a regular mouse allows me to be pretty fast with the mouse. Early Pro’s: 1. Bluetooth connecting is really easy. 2. Kensington Works software for the trackball is easily downloaded for the device and pretty easy to use although it is not overly intuitive. 3. Large trackball seems very good particularly located in the mid position. Is good for me with some tremors and a shaky thumb compared with a side trackball. The middle trackball is far superior, for me, to the side mounted track balls. With practice, I am sure that I can rapidly move the cursor via the trackball. 4. Left Click/lower left button works pretty well. I seem to have it pretty well figured. Using my thumb for this button. 5. Right Click/lower right button not so handy as the Left Click button. Learning. May do better with it after more practice. 6. Have not really used upper two buttons, yet. 7. Scroll ring works well. Don’t have clicking noise that other reviewers have reported. 8. Don’t know how the battery life will be; we shall see. 9. Don’t yet know how the wrist rest will be although it seems okay with this short time review. Early Concerns: 1. Will take considerable practice for me which I am willing to do to become proficient with the trackball. 2. Have already learned to be very careful not to simultaneously touch the trackball while trying to scroll. Is easy to do! Result is my inadvertent action takes me some crazy place I did not want to go!

## Questions & Answers

**Q: Does it work on Linux?**
A: Yes. I’ve used this trackball with 5 different releases of Linux Mint going back some years. All 4 buttons will work, but you will have to monkey with your desktop environment to map them to what you want.

**Q: does left click result in double click after use?**
A: I have a Kensington "Mouse Port/Serial" version (RS232 "COM" Serial or PS/2) Expert Mouse trackball (from the mid 90's) that I bought new all those years ago when I built my Intel 486 DX2-66 PC (66Mhz = 0.066Ghz) and have been using for hours and hours every day on each PC upgrade I've built ever since (currently a i7-4790K !), including audio editing, gaming, web browsing, and more...  I still have the original box which says "OS2 Warp" and "Works with Windows 95 and Windows 3.1" and "5 Year Warranty" on it (yes, it's really THAT old!) and all these years later I'm now using it on a 4.0Ghz quad-core PC running Windows 10 Pro x64 with no problems whatsoever! Even after pounding hard on the bottom left button for gaming year after year it just took the abuse and kept on working fine. After about 15 years of that abuse along with lots of hard pressure holding of that same bottom left button for selecting audio segments, manually scrolling through documents and web pages, and so on, it began occasionally either releasing or double-clicking during selecting of audio segments as if I'd released the button when I had not, BUT after sitting overnight it always goes back to normal and doesn't act up like that unless I start doing lots of heavy thumb action with bottom left button holding or pounding again. If I remember to go a little easier on the pressing or don't do a ton of left button holds it can go for weeks before the bottom left button gets quirky again. Also note that it's literally 20 years old, it's been doing that off and on for about a decade now, and it has never been anywhere near as intermittent and downright useless as the Logitech buttons become in less than a year with comparable use. We have Logitech trackballs at work and after the third replacement batch in 2 years they've learned to live with the flaky buttons because the boss feels that $25-$40 for a mouse is absurd and he definitely won't spend the money to buy Kensington trackballs... I'm actually about to replace my 20 year old Kensington Expert Mouse with the new model, only because I need a KVM, my back-lit keyboard is "USB only" (PS/2 Support), USB didn't exist when I bought my now 20 year old Serial/PS-2 Expert Mouse, and although I have successfully gotten its' signals to convert to USB through a (RS-232 COM Port) "Serial to USB interface" and also got a PS/2 to USB keyboard/mouse signal converter dongle to work with it I haven't been able to successfully get either of those converted USB signals to pass through a USB KVM...I started to look for other ways to adapt PS/2 or Serial to USB that claimed to be KVM compatible but I couldn't find a workable solution that would pass through a USB KVM for less than the cost of a brand new Kensington USB Expert Mouse so sadly I think my 20 year old Expert Mouse is about to be retired and an new USB one will finally be taking its' place soon. I hope the quality of today's Kensington Expert Mouse is as good as they were 20 years ago. Time will tell... Also note that my 20 year old Expert Mouse that still works very well uses 2 giant wide metal rollers for the X and Y axis motion detection (that the ball rests on) with photo-led sensor wheels inside to generate the X/Y mouse movement signals, basically over-sized industrial grade versions of the small plastic roller rods the old rubber ball mice used to use (which had to be cleaned when the cursor started getting stuck and I need to clean these maybe once every 3-4 years at the most), unlike the much newer mouse technology of the past decade that uses optical detectors to actually look at the ball and see it move. As a comparison, Logitech once offered a big track ball mouse for a while that looked almost identical to the Kensington Expert Mouse for less than half the price and when I lifted the ball out to check out the rollers it was immediately obvious why the price was so much less.  They were tiny rollers just like you'd find inside a cheap old ball mouse! So 20 years ago you got what you paid for, and even 10 years ago it was obvious that the Kensington products were still vastly superior in quality to their competition and based on the reviews here that still seems to be the case.

**Q: Can the Expert side scroll?  I use spreadsheets that are really wide and have a lot of columns and need that feature.**
A: Even better than holding the SHIFT key, you can scroll horizontally ONE-HANDED: Assign one of the additional buttons to activate the SHIFT key using the included KENSINGTON TRACKBALL WORKS software. I recommend using the button opposite your thumb so you can use your thumb to scroll horizontally. So, for those RIGHT-handed assign SHIFT to the TOP RIGHT button, for LEFT-handed assign SHIFT to the TOP LEFT button. This works on Windows and Mac OS X.More Info: http://www.kensington.com/us/us/6498/trackballworks%e2%84%a2-customization-software

**Q: Does the scroll ring on this mouse have clicks that you can feel while scrolling - when scrolling through a set of images to be able to know that you**
A: No, I don't know if the people above had a different version of the mouse or something but there are NO clicks on the scroll ring. It scrolls smoothly.

### ⭐⭐⭐⭐ Well made, works great, not great for carpal tunnel
*by C***A on January 26, 2026*

It's sharp looking but made my carpal tunnel worse. I like the ball control and big buttons, but the upward angle, even with the included wrist rest, still caused more pain than a mouse was. Other than the pain, it works great. I do not use it for gaming so cannot speak to that, but the ball rolls smooth and is easy to remove and clean. I really enjoy the center ring for scrolling.
