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: Love my Slimblade - I got the Slimblade Trackball for my office, to be used alongside a TypeMatrix keyboard and a Func MS-3 mouse. It took a little while to get used to, but what a brilliant tool! Arm movements are no longer necessary, which means less pain in the neck and shoulders. Letting the ball glide by itself also makes travelling long distances on the screen much easier, which is ideal for a dual-monitor set up. And while scrolling is a little disconcerting at first, I now vastly prefer it to the scroll-ring on my coworker's Expert trackball. Although not as advanced as they could be, the drivers let you configure your Slimblade pretty much any way you like. I'm especially a fan of the shortcuts you can assign to any button or button combination. I configured mine to close the current tab/window when I press the two top buttons and it's just a joy to use for my daily browsing. I still keep my mouse around, mostly for Photoshop and other similar programs, but prefer using my Slimblade for 80% of what I do on a computer. If Kensington ever gets around to updating this product, here are the only areas of improvement I can think of: - Heavier base plate (ideally made out of metal) to prevent the trackball from moving around during intensive use. - Improved drivers. Most notably, I would like to have a way to manage several trackballs (ideally I would like to have a trackball on each side of my keyboard which would mirror each other: eg. the bottom left button of the trackball on the right would be the same as the bottom right button of the trackball on the left).

## Features

- Sleek Design - The low-profile shape along with the silver metallic finish offer beautiful aesthetics and ergonomic comfort. The trackball takes up less desk space than what is needed to operate a mouse and is more comfortable during extended use because it requires less arm and wrist movement
- Precision Movement - Laser technology provides highly accurate and responsive cursor tracking and scrolling, plus the large 55mm ball makes it quicker and easier to navigate anywhere on the screen. Scroll up and down web pages and documents with a simple twist of the 55 mm ball
- KensingtonWorks Software - Allows you to truly customize your productivity experience by letting you adjust the cursor and scrolling speeds, as well as the functions for the four buttons including media player controls. Compatibility: Windows 7, Windows 8, Windows 8.1, macOS 10.8, Windows 10, macOS X 10.11, macOS 10.10 or above, Chrome OS 44 or above, macOS 10.9, macOS Sierra 10.12
- Plug and Play Installation - Simply plug in the USB cable to your device and you’ll be up and running quickly as the drivers will download automatically, plus there’s no need for batteries
- Ambidextrous design ideal for both right-handed and left-handed users
- Wired 150cm USB cable provides reliability and avoids need for batteries
- Improve your productivity, increase cursor control and save desktop space

## 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.
