## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Love it!
*by A***A on 3 April 2025*

I used a Kensington trackball before but this is another level. Extremely comfortable for my hand given the perfect ergonomic shape, the ball is big but that's also why it's so nice to move, but the best feature is the ring. I love how sensitive it is to small movements. Yes, a bit plastic-y, but after a bit, you get used to it. It moves so smoothly and I can really calibrate how I scroll a page in a very intuitive way. Really great product. I bought the wireless one first (red ball) but then I realised it's battery-operated, so I swapped it with a wired one.

### ⭐⭐⭐⭐⭐ Traditional mouse to a Trackball has been a life saver
*by L***A on 7 March 2025*

After months of misery using my traditional mouse, I decided to give a trackball a shot. The first two were no good and were sent back (don't go for one where you have to use your thumb to turn the ball), but after procrastinating about it, I decided to try the Kensington Orbit Scroll. To say I am in love with a mouse is an understatement. First off, I can use it with my left hand, which felt a little strange for a few days, but now feels completely normal, giving my right hand a complete break and hopefully some healing time. It is so easy to use - 2 buttons and a ball, plus the scroll wheel which is an absolute game changer for me. If this hadn't been successful, I was going to try the Slim Blade Pro, but quite honestly, I am really happy with this and have no plans to change it for a while.

### ⭐⭐⭐⭐ Works perfectly with Linux, comfortable to use
*by C***N on 12 March 2025*

dropped a star due to the price but it is a good quality item so maybe I'm being a bit harsh. It works exactly as you'd want it to and the scroll wheel is very good. Overall I found all the functions responsive and accurate. It's comfortable to use, well designed and the ergonomics work well. It sits flat on the desk and whilst bigger than a standard mouse it needs less space because it doesn't move around.I've seen some questions on here so I can report that it works perfectly on my Linux Mint 22 system. No setup required. Just plug in the USB and away you go. No extra drivers needed.I don't use it for gaming so I can't comment on that aspect.
