Review: Excellent piece of kit. - I originally bought a Trackball for my Mother as, after breaking her wrist in a fall, she developed Arthritis in her wrist and found using a normal Mouse not only difficult to operate but caused a great deal of pain after a short while. The Trackball meant that she could rest her arm comfortably on the desk with her wrist supported, and mainly operate her computer using just her index finger to move the Ball and left thumb to left click with, (right click was usually her third finger right hand). The Ball is easy to control and moves very easily when just flicked across as one does with a moblie phone screen. The only downside is that it does not have a scroll wheel so you have to use the scroll bar on the side of the screen to scroll up or down, ie left button press and hold down, then use ball to scroll up or down. I have found that leaving a normal 'wheel mouse' connected for these occasions is the answer. Overall, having bought one for myself as well, I find the Trackball easy to use and it is much kinder to ones wrist especially when having to use the computer for any length of time.
Review: Love these - I first started using a trackball mouse at work because I was getting a constant ache in my shoulder, which I put down to the movements using a regular mouse (my job involved me being on the computer most of the day). Once I'd been using the trackball for a week or so, I noticed that the ache was easing up, and it soon disappeared. People at work struggle to use my mouse if they come over to my desk to show me something, but I took to it from day 1. I find if I try to use a regular mouse now I struggle until I get used to it. Great gadget, and very useful if you have limited room as it doesn't need to move - the ball on the top does all the work. I have 1 for both my home computer and laptop (can't get on with the laptops built in mouse at all). Kensington also do a trackball mouse that isn't optical, but it's worth paying that little bit extra for the optical. The other type picks up more dirt and fluff, which sticks to the rubber rollers that the ball sits on, the movement of which controls the curser. You have to keep cleaning the rubbers, and eventually they wear so the ball can't get any traction. The optical mouse still picks up fluff on the 3 little balls that hold the trackball, which also causes it to lose traction, but you just wipe off the fluff with finger or tissue and you're off again.

## 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

### ⭐⭐⭐⭐ good price and mostly great
*by M***S on 26 October 2009*

I recently went from using a laptop to using a desktop set up next to my computer, and as my old wireless mouse kept falling off the bed and a book didn't make a good mouse mat I decided to get a trackball mouse. This is something ive pondered for years anyway. I looked at this one and the similarly priced one from Logitech Logitech Marble Mouse , but decided on this as the activation of the scroll function (pressing both buttons simulateously) seemed easier. The product itself is good quality, there is a disadvantage that the ball just sits in its hole, meaning if you are going to be moving it about alot it could get lost. The buttons are quite large and register a click wherever you press on them, which is very good as this makes it easy to position your hand on the mouse in different places and accommodates different hand sizes easily. The ball is quite sensitive, and takes a bit of getting used to compared to a normal mouse, but i expect this applies to all trackballs. You can adjust the sensitivity of the ball and lots of other things using Kensington mouseworks. This is where this product failed most, because Kensington didn't include this software with the product or put it on their website on this products page! It can be downloaded free at popular software download sites, i think they're on about version 6. Once you have mouseworks you can set up the scroll function, which is activated by pressing both buttons together (although you can adjust the lapse between the two buttons to make it easier to activate), then the ball is a big scroll ball until you click again. However i have not been able to scroll horizontally, which can be annoying, and the default speed is quite slow, but this can be sped up, but on some applications (particularly ones like google earth where you use the scroll to zoom in and out the scroll is far to sensitive and before you know it you're on street level! One other minor irritation is that when your hand sits very far forward on the mouse and your fingers are on the front side of the ball it often lifts up slightly, which is annoying. Also, rather strangely (and quite possibly my computers fault) i initially started using the mouse in the PS/2 slot, but one day it just didn't recognise it, but it worked fine in a USB slot. Overall a good price, and a good mouse with a fair amount of functions, just make sure you get MouseWorks to go with it.
