From the Manufacturer
The Kensington Orbit Optical Trackball offers the comfort of a mouse with the benefits of an optical trackball. Control your cursor with a simple touch of the finger! The highly accurate Orbit Optical is as easy to use as a regular mouse, but it stays in one place, saving you valuable desk space. Designed for PCs and Macs, the Orbit Optical Trackball employs Kensington's Diamond Eye optical technology for smooth, precise cursor movement. Diamond Eye provides unmatched acceleration control, combined with ultra-high speed optical optical technology to produce the ultimate in precision and accuracy. The precise optical tracking mechanism is also resistant to dust, reducing the need for regular trackball cleaning.

Customer Reviews

The Best I've Found!
I used the old ADB version before this one and they're both amazing. It's the only mouse that keeps my wrist from hurting after multiple long days of work.
Some of the finish gradually wears off, but mine is still working 100% after having it for 4+ years, and only needs cleaning every few weeks.
I've tried finding a different mouse several times, just to try something different (or something with more buttons, scroll wheel, etc) and every time end up back with the Orbit.
Something to note, is that it's not a trackball - you don't control it with your palm. You only use your fingertips, allowing you to put your arm and hand in a comfortable position and leave them there.

good item
very happy with the trackball. I am on the computer a lot and have pain in the arm and elbow, this has helped so much.

The best mouse.
I just bought my third Kensington trackball mouse. This is a really great mouse. Unlike the Logitech trackball (which I bought and subsequently replaced), the sensitivity and "feel" are just right.

The biggest advantage of a trackball is the ability to get your cursor in exactly the right place, and then release the ball (i.e. the positioning mechanism) prior to clicking. In this manner, the cursor won't move as you make the click. This has real advantages for the graphic artist.

Another advantage is not running out of mouse pad or cord, since the mouse itself stays stationary. It takes up less room on your desk.

I don't believe it would be a good mouse for gamers, though I do not use my computer for games and perhaps there are some settings changes that would allow it to be used for such. It's more of a precision instrument.
