Kensington Ergonomic Expert Mouse - MSRP $99.99 4 5 69 69
Great trackball I have used KEM's for many years, and have loved them. Both my wife and I have arthritis issues, and mousing for long periods is painful. The KEM has been a great solution over mouses and marbles. Most of the stickiness issues have been from my greasy hands, but a gentle cleaning quickly corrects the problem. I just wish it worked well in Linux--very hard to configure. July 23, 2015
Even better then my last one. Still the best design. Ball was a little "draggy" at the start but getting smoother with use. July 20, 2015
Excelence Been on heavy duty here for +10 years. Robust, configurable and easy to use in long office hours. July 18, 2015
Kensington Trackballs are the best!!! Even though they call this trackball a "mouse" I forgive them because it is awesome. I have converted 50+ people from a mouse to this trackball. I tell them use it for a week. If you don't like it I will buy you the mouse of your choice. I haven't had a single person not like it. It usually takes a few days to convert them but they gush with thanks after the week. I haven't used the software that is comes with in a long time. There are many macro programs that are not device dependent out there. I use this device A LOT. I have been using their trackballs for 13 years or so and nothing else comes close. I do agree that the scroll ring has issues, can feel rough and stop working. The little Teflon ruby balls can get lost when you are cleaning it. The optical sensor can start working sporadically and is unfixable. With that said Kensington support is awesome. They quickly address my issues, ship the parts quickly and are always helpful and cordial. July 9, 2015
Expert Mouse is only mouse I use. I have used the Kensington Expert Mouse for graphic design for more than 15 years. Any time I have had an issue with the product (which has only been twice in 15 years, Kensington sent me a brand new replacement asap! June 18, 2015
The Only Mouse I Need My work got this mouse and after using it for months I decided to order one for my home office. I don't have anymore wrist/forearm pain and it's so easy to use. The customizable buttons made learning easy. I've made the switch to trackball and I'll never go back! June 18, 2015
software does not work I bought this because I like trackballs, the software does not function all it tells me is there is no device attached. I can not figure out how to uninstall the software to try again June 16, 2015
Great trackball (for $40) This trackball is smooth and I love the extra buttons. I've been using some form of Kenginston trackball at work for over a decade. The main problem with this trackball? The SCROLL WHEEL STINKS! It feels cheap, spins terribly and always seems to be dirty, even when it's brand new right out of the box. It makes this quality device seem very amateurish. I've waiting years to buy this trackball because the price was too high for such a cheap scrolling mechanism. When I was able to purchase new for $40, I jumped as the rest of the trackball features make it worth the purchase at that price. June 6, 2015
