The Kensington Expert Mouse Trackball is like no ordinary mouse . I got this mouse as a gift. However, I did a Google search and this mouse costs $119.99. I, personally, feel that this mouse is over priced. I had expected this to be roughly 60 dollars. This mouse is nowhere near what I had expected.

The Kensington Optical Expert Mouse trackball mouse is designed to be an alternative to the traditional version, with the cursor controlled by a large weighted ball.

I was pleased with the trackball, as many of the people in the post production industry use it. I was very happy with Kensington supplying a wrist rest in the box. The motion of the ball is very smooth and highly accurate.

Easy To Clean; Ergonomic Layout; Smooth Movement

Have used a trackball for about 12 years. I compare using a trackball vs a regular mouse to be like riding a no-speed vs a 20 speed bike. Wouldn't be without it. And you do get what you pay for. The last Kensington Expert Mouse I purchased (before this recent purchase) was in Jan 2000.

Yes, I would recommend this to a friend

Comfortable Design; Easy To Clean; Great Features; Highly Compatible; Quiet; Reliable Performance

I was so excited to see this trackball not only that it is wireless but also a new look, the red ball and black Matt color that it seems like something out of Star Trek, LOL. The Spinningwheel is not as smooth as my previous wired truck balls but I think that will just come with time and usage...

This is excellent for people w/ carpal tunnel or other "grip" problems. The grooved circle around the ball is great for scrolling. Regular mice strain my thumb & wrist. But if you need a mouse for gaming, this is not it. The gamers in my house hate it.

Ive used the various incarnations of the Kensington Expert Mouse for nearly as long as Ive used a pointing device on a computer yeah, I was a late adopter of Windows, I held onto DOS as long as I could. No mice needed with DOS!.

Large ball; smooth motion; easy to clean

Hard to find out there, except for some specialty stores, or on line; Misleading name! Why is it called an Expert Mouse ..; when its a trackball

Bought two. Been using this for years after some elbow pain using regular mouse. No more problems & large ball is easy to maneuver. Plug it in & it works.

This is the eighth Kensington trackball device that I've happily owned over the last 20± years. Having just purchased my 10th Mac-the new iMac 21.5", 3.2 GHz-I naturally "tried" Apple's new wireless bluetooth mouse.
