Pros: o Extremely reliable - owned a Trackman Marble /out wheel) for 3 years and it is showing absolutely *no* signs of wear and tear. None. o Performance - excellent response and control o Ergonomic - comfortable, pretty much molded to the shape of your hand. Funny how 1 size fits all....

Review of Logitech TrackMan? Marble? trackball mouse. **The Product** ~~Why I bought it!~~ I have long been a fan of the Trackball style of mouse as opposed to the tradition type. When I used mainly my PC computer, I always used a trackball as a matter of course and had a Logitech version.

Less wrist strain; easy to set up and operate

Pricey in comparison to traditional mouse systems

This is the best mouse I have used in over 15 years of using computers and mice. Having had surgery for Carpal Tunnel Syndrome (pressure on nerves in wrist joint) which has not improved matters, this mouse takes the strain out of PC/Mouse operations.

Yes, I would recommend this to a friend

Accurate Controls; Doesn't need alot space; Easy To Clean; Ergonomic Layout; Fast Response; Smooth function; Smooth Movement; Very long lasting

Tends to get dusty

This trackball mouse is excellent! It's the only mouse that helps with my wrist fatigue. I am on the computer 40+ hours / week and couldn't do it without this mouse.

Smooth Movement

None

I like trackballs, especially the ones that allow manipulation of the trackball with your fingers instead of your thumb. The Marble Mouse is ambidextrous, which makes it more usable than other, right-handed models.

Accurate Tracking; Comfortable Design; Fast Response; Glides Smoothly; Works On Any Surface

No Scroll Mechanism; Secondary Buttons Small

I finally gave in to my curiosity and purchased one of these when my 9y.o. Logitech "normal" mouse gave out. Gotta admit, I hated this thing at first, but now I can't ever see myself going back.

Smooth; accurate scrolling; Uses way less workspace; Easy to keep clean

None

My whole family now uses this trackmaster style mouse. Easy to use and years and years of use. Never miss a beat.

Not the best of Logitech's, but second best. This is my 5th. The best however was the old "Trackman Marble FX" which they don't make anymore unfortunately. Using a trackball is an instant cure for carpel tunnel syndrome you get from using a mouse.
