## Description

Buy

Review: Buy the trackball & seperate mouse mat, GET THE RIGHT SOFTWARE! Great for Lefties / Ambidextrous. - AMENDED - I GOT THE RIGHT SOFTWARE, SET IT UP, REBOOTED AND IT STILL WORKS - OH FRABJOUS DAY... BUT YOU HAVE TO RUN IT MANUALLY AT STARTUP - ROYAL PITA! Generally I only use the lower buttons, uppers are set at double click & back, so used to control click / open from Mac Contextual Menu. MAYBE it's just me, but for an optical device it can stick after cleaning; polish the ball carefully afterwards. I LOVE Kensington products. BUT since the end of software on a disk, it's tricksy. I downloaded & installed the software for my all in one printer no problems, but this! I made one last try as I was getting sick of only 2 functional buttons. IT HELPS IF YOU HAVE ANOTHER POINTING DEVICE AS A BACKUP!!!!!!! I have a cheap wired trackpad, PITA to use but works. 1: goto KENSINGTON site. 2: find EXACT picture of device, select. 3: scroll down to downloads, you want KENSINGTONWORKS - NOT TrackballWorks - check INSTALLATION NOTES that it has the driver for the EXACT device. 4: download, launch from start menu. 5: play with the settings - there are TONS of them, keep fine tuning until it's right for you. 6: if you're still not happy you are a bigger PITA than me - well done you! I have rechecked EVERY setting I can find - Oh how I miss Apple Macs (but TOO expensive and poncy these days) - as far as I can tell, my system is STILL recognising it only as a "Kensington Expert Mouse". BUT the software works now so who cares if the PC calls my Trackball "Felicity Bumsquash". Trackball Works DID NOT detect my trackball, Kensingtonworks does; also does not crash the computer like TW. I know, i'm demanding. WHY Kensington do not just ship with the software on a USB stick is beyond me. Or even a DVD - it costs around £30 to buy a DVD-RW drive AND you can play CDs and DVDs AND burn CDs & DVDs! Showing my age I suppose. I remember my first home computer - Sinclair QL128 (Kb) with MICRO drives on a portable telly! Hours of fun waiting for programs to load; then crash ... repeat until the drive cartridges broke - happy days! Then Atari ST 520, 2, 4 with Disk drives and WINCHESTER drives as an expensive optional extra... PC, Macs, Android and back to PC. ANYTHING but Uni mainframe terminals! ALSO, I recommend >>>Kensington Mouse Mat with Wrist Support - Ergonomic Duo Gel mouse mat, compatible with laser and optical mice for comfort when at computer, laptop, office, PC, gaming - Red/Black (62402).<<< WITH an extra mouse mat wrist rest if you lean your elbows over the table, not freeishly hovering. Essentially you need around 4 inches of support to use this device, go by the supplied one as a guide - but it hurts (me anyway) to use it. Not that colour particularly, but it has plenty of space for the device and, for me sits above another mouse mat wrist rest so is MEGA comfortable. The one supplied just does not cut it. All in all I am satisfied NOW that I spent £80 for a trackball. I had a non optical one on Macs, wasn't around when I had my previous PC; now there's no mucking around with alcohol, Q Tips and tweezers trying to clean the rollers. Minivac and a screwriver if it got too bad. Just wipe the ball and innersocket. They are different, expensive, but so much easier and actually reduce wrist stress especially combined with an ergonomic keyboard. GREAT for arthritis / rheumatism / nerve damage (i'm dyspraxic, nature of the beast). Oh and finally I found the scroll wheel - it's a flipping dial - it's a ring surrounding the ball - PITA to avoid pressing a button! slight ridging so easy to find by touch and use. BUT you CAN adjust it in the Kensingtonworks settings too!!!!!!! Yes I do love playing around with settings, 50 something going on 5 with technology.
Review: My favourite pointing device ever - I am a programmer, and spend a lot of time in front of computers: I generally use a computer for 7 hours each day at work, and also use one a lot in the evenings at home too. For the past few years I have been experiencing muscle twitches and spasms in my arms and hands, especially in periods where I have spent extra time on the computer. A while back I decided to buy a trackball, and bought a Logitech thumb trackball. I really liked it, but after a while some of the buttons stopped working properly, and I also found it difficult to move the ball forwards and backwards with the same speed and accuracy as I could move it side to side. A few months ago, I bought one of these trackballs to use at work, and I absolutely love it! I find it so much easier to use than the thumb trackball, and I find it easy to use with my left and right hand, which means that I can switch hands when I get twitches or pains. A week after buying this I bought another one to use at home so now I own 2! A lot of people have complained about the scroll wheel feeling cheap and scratchy, and I even read somewhere that it feels like it has sand inside it! This is definitely true when you first buy the unit, and it still does feel like that to some extent, but the action of the scroll wheel gets better and better as you use it and feels much more fluid. I have used this trackball with both Linux (Ubuntu) and Max OSX and it works fine with both of them. The (unofficial) Ubuntu driver is brilliant, as I can set one of the buttons to be a scroll button. If I tap it, I have set it to navigate backwards, but if I hold it down then the main ball works like a scroll wheel which is really smooth. Unfortunately you can't do this with the Mac driver and I don't know if this is possible on Windows. Overall this is the best 'mouse' I have ever owned for general usage (I have a regular mouse for gaming still), and takes up a lot less space on my desk than a regular mouse as I don't have to move it around. I don't think this has cured my RSI on its own, but it definitely helps as I can switch back and forth between this, my thumb trackball and a normal mouse depending on the state of my hands. I 100% prefer this to a thumb trackball. Edit: 5 Years later this thing is still going perfectly. The mouse wheel is smooth, I get less weird muscle twitches in my thumb and it's a joy to use. I definitely recommend this.

## 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.

### ⭐⭐⭐⭐⭐ I absolutely love it!
*by B***E on 23 March 2010*

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!
