I have used one of these for years. Great control, no moving the thing around, great for limited space desks. As for those who complain about not having a scrolling function, it is on the disk that came with it, install the software and you've got it. HIGHLY recommended!

This is my 3rd Logitech Trackman Marble Mouse. Must be something that I like about it. A couple of years using it to play Skyrim and then it is time to get another one. Skyrim must be pretty rough on it.

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

I'm not saying this is a bad mouse, it's a great one, that allows precise tracking and greater comfort than the vast majority of the market.

When I first purchased this mouse, to replace my original, standard 2-button mouse, I was hoping for a fantastic, revolutionary replacement. I don't think I have been let down. When I first got hold of it, and set it up, useage was slow and difficult to say the least.

Ergonomic design; Ease of use; Low desk-space usage

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.

I have a very cluttered desk so my mouse was not getting frustrating to use. I bought the trackman thinking it would just be a capable substitute, but it exceeds the mouse in every way except scrolling... Find a way to improve the scrolling and it's pretty much perfect.

I've bought almost every trackball ever made in the past twenty years - each one excels at one thing, fails at another. I have yet to find the perfect trackball. This one is without doubt the most comfortable one I own: it's a great shape for the hand and the exposed trackball gives you huge control...
