Customers are mixed about the size of the mouse. Some mention that the size is fine if you have limited space and like small devices. However, others say that the mouse is very small and very low to the desk, with the ball being just way too big. The dongle is not as compact as Logitech dongles, and the bearings are way too small causing loss of contact with the mouse ball.

"...factor was either way too tall and short length wise, or the ball was just way too big/heavy (maybe they will figure out a good design eventually)...." Read more

"...The plus is the scroll feature, it's unique, and encircles the base of the ball. It works much better than the "wheel", in, IMHO...." Read more

"...The wrist rest needs to be wider too and not too narrow. For smaller hands this would be find but for larger hands the Expert Mouse is nicer...." Read more

545 customers mention129 positive416 negative

Customers find the buttons on the mouse difficult to click, require too much force, and double click on their own. They also say the mouse is missing a middle click button and the buttons are too far forward.

"...find that sometimes in certain programs like a Flash game, it won't always want to click on the first try, so I wouldn't recommend this for gaming..." Read more

"...I don't understand why the buttons are not shifted back, at least a tiny bit further on the device (with exception to internal design restrictions)...." Read more

"...It only has two buttons, which was fine by me, so that wasn't a turn off for me. The downsides I found with this trackball were the extremely..." Read more

"...The software also permits configuring the function buttons and reversing the action of the scrolling ring...." Read more

Works fine but footprint is too large
3 Stars
Works fine but footprint is too large
The Logi Trackball to the left is no longer available but is a much more functional design. 1) Ergonomics: with the thumb centered on either of the buttons, the forefinger centers on the trackball. However, with the Kensington, the forefinger's joint is what centers on the trackball - more awkward. 2) Footprint: The Logi is only as wide as it has to be and doesn't take up more with than necessary on the desk. It is longer, however with a keyboard, width is what is in short supply.I continue to keep my Logis alive but hope that someone will buy out the design (or whatever patent rights prevents other companies from providing a truly good solution.) The importance of this ambidextrous design is that at the slightest sign of carpal tunnel, we can switch hands. Both trackballs solve this problem at least. In my opinion a right-hand-only or left-hand-only trackball is useless to someone who uses it all day (and I am not a gamer.)
