Review: Quality device, well worth a look for mouse-related RSI/Tendonitis sufferers - I've been suffering from mouse-related elbow tendonitis since late last year, so I have been through various pointing devices trying to find one that will not keep damaging the tendons. Finally, with this trackball, I have found a solution ... not just in helping with the tendonitis, but also in feeling easy and natural to use. As a hardened mouse user, I was initially wedded to the idea that I needed to find a better mouse. So I tried various "ergonomic" alternatives, but I realised that my problem came from the left-right pivoting of the elbow, and not from the angle of my wrist or the stress of pressing the buttons. In fact the "ergonomic" mice I tried made things worse, since being wireless they added the weight of a battery to the mass I was pushing around. One or two small batteries doesn't sound like much, but it's all extra load on a problem joint/tendon. Next, I went for a Logitech M570 trackball. I found steering with my thumb clunky, and the trackball was not pixel-accurate; it jerks by several pixels when you move it, rather than rolling smoothly. Cleaning and lubricating helps but does not completely solve the jerkiness (in fairness it's fine for general desktop use, just not for pixel-perfect control). The final drawback is that the M570 is right-handed device; I used it for a period with my left hand in order to allow time for my right elbow to heal, but it's not designed for this at all. I also tried a Wacom tablet, but again moving the stylus put stress (if less than with a mouse) on the damaged elbow. Then a few weeks ago, I happened to see one of the large Kensington trackballs (it was in a producer's intro to the Battlestar Galactica box set; he was sitting in front of an editing system with a Kensington Expert trackball front and centre). As soon as I saw it, I instinctively felt it was the kind of thing I needed. I searched for "Trackball with large ball" and soon identified it as a Kensington device; a SlimBlade soon arrived and now, a few weeks later, my elbow is not troubling me at all and I'm as comfortable using this, as I used to be with a mouse. The large ball has a definite feel of "heft", running smoothly and allowing pixel-perfect placement. So for me it has been worth every penny, even allowing for the rather high price. I have spent more than that price on trying other solutions that didn't work for me. The initially-released software was rightly criticised but the latest version is fine, allowing each button to be programmed with a different function, as well as being able to detect when the top pair or bottom pair of buttons are pressed simultaneously, giving six functions overall. The "twist ball to scroll" feature feels completely natural, and is the main feature that sets the SlimBlade apart from the slightly cheaper Expert. But I'm sure that an Expert with its physical scroll ring would do just as well, and it offers the benefit of coming with a wrist rest ... however I don't personally feel that the SlimBlade needs a wrist rest because of the way it slopes gently down to the desk -- and it would be easy enough to improvise or purchase one if needed. ----- Updates following a few more weeks of use: LUBRICATION: lanolin is apparently what Kensington uses for lubrication at manufacture, and is thus perfect for re-lubricating the ball if necessary. I just moisturised my fingertips with a tiny amount of solid, 100% pure anhydrous lanolin, and then used the ball for a few seconds, and a day later it is still gliding like new. GAMING: I got around to playing a first-person shooter with the trackball, and am happy to report that it works for me just as well as a mouse. Equivalent control, but no more running out of mouse-pad! The only disadvantage is that your index finger is naturally used to steer the ball, so you may need to map a different control to fire weapons etc. But overall, FPS gaming is at least as enjoyable for me with this, as it was with a mouse.
Review: The Kensington Slimblade is the only trackball I use - So I bought the Slimblade trackball way back in 2014 and I still use it to this day on my custom built Windows 10 64-bit computer. The only software you need to install is the Kensington TrackballWorks 1.3.1 and with that I'd suggest a few changes, such as changing direction in which you spin the ball to scroll and adding the "drag" function to one of the buttons. You can customise how you use the trackball in various other programs, and even add more functions to "dual-clicking". Honestly I like to keep my usage simple and easy so I have tried them but have stuck to the basics. So why a trackball? I like the slim, almost minimalist design. It's a sleek, almost timeless design and yet it's also very functional. You don't need a large desktop area nor a mousepad either, which is good in keeping my desktop clean and small. Some things can be improved though, perhaps the material paint around the trackball, or the "loudness" of the click, I'll mention this later on. The other main issue was wrist pain, I used to play a lot of games and do a lot of video editing which involved constant dragging which caused my right wrist to hurt. Along with a few other changes, such as posture, changing my computer chair and getting rid of the mouse, my wrist has not been in pain from using the trackball. I can still play games with no problems, perhaps better than before. I love how effortless it is to scroll through a webpage, it's a small, perhaps under appreciated thing. Maybe a certain gaming mouse has a free turning, weighted scroll wheel that helps alleviate the constant action of flicking your middle finger, but with the slimblade you're actually scrolling at an angle which reduces more stress from your finger, it's hard to describe but the feeling is different and better. If there is one thing, I wish they would update the model, maybe work out a few new colour schemes that would reinvigorate their product line. I have a few nitpicks though, a slight QC/design issue I have is with the chrome ring paint chipping just by the left and right click pad (especially if you have long finger nails) and how it sometimes doesn't register your scrolling due to dust surrounding the trackball sensors. That part is easily cleaned and rectified though. Overall, while it might seem pricey, I haven't come across any trackball alternatives that rivals the Slimblade in quality and design. I'm still using it after all these years.

## Questions & Answers

**Q: Is there a way to use top right button & bottom left together (& vise-versa) to make a new command for the Kensington Expert Mouse?**
A: You must install the Trackball software, which starts every time you reboot.  it's a free download from Kensington's web site.  With that you can define a function when you click both buttons together, and also define what each button does on its own.

**Q: Does it have Windows 8 (specifically 8.1) support?**
A: It works fine with my 8.1 x64 install

**Q: Are these easier on the wrists considering that the pictures show hands in the horizontal position, which is usually bad for your wrists.**
A: I've been using a variety of trackballs (finger operated not thumb-balls) for months now and I can't go back to using a mouse. i've had literally zero wristproblems since switching for everything (even gaming) and whenever I'm forced to use a mouse even for a short time now I am quickly reminded of my arm / wrist aches again.

**Q: can it click lock**
A: yes use windows mouse settings

### ⭐⭐⭐⭐ Almost the perfect trackball.
*by C***E on 17 September 2015*

I started using a trackball a few weeks ago, it does take some getting used to if you've been using a mouse but they are a lot more comfortable and more precise once you've adapted. Having started off with a cheaper model to see if I'd like the ball, I decided to upgrade to the Slimblade. This thing looks gorgeous, the large ball has a nice weight to it and rolls nice and smoothly. The four buttons are well-positioned, and scrolling by twisting the ball works really well, you can also do this with one finger by running it around the chrome ring and rotating the ball which make scrolling without moving the cursor a piece of cake. The slim profile also means that it is comfortable to use without a wrist rest. Don't worry about the bad reviews criticising the lack of customisation for the buttons, this has now been addressed and if you download the TrackballWorks software from Kensington you can customise all four buttons. It's not all good though. The trackball rocks ever so slightly on a desktop, I fixed this by putting a couple of squares of masking tape over one of the feet but you should not have to do this. The other thing is that it emits a faint squeal constantly. You can only hear it if the room is pretty much silent, but it is quite annoying. The buttons also click very loudly, but I'm hoping that this may quieten down with use. It's not perfect, but it's very comfortable and pleasant to use so I'm happy with it overall.
