Logitech Marble Mouse (904360-0215) Trackball

Pros: silky smooth trackball action, natural fit in hand
Cons: left and right click takes getting used to

This trackball rocks! After being with a crummy "ball" mouse for almost eight years, 7 on a desktop and 1 on a laptop, this was like manna from heaven. And don't even get me started on my laptop's horrid trackpad...

I bought this trackball after Christmas because my mouse was giving my hand aches and pains, for I am a student who constantly uses the mouse. As soon as I opened the box, I was immediately amazed at how comfortably it fit in my hand. Once I configured the Marble Mouse for my computer, I was up and running working on school projects and essays...and the occasional game of Rainbow Six 3...

The ball action is smooth, with just enough resistance so the cursor doesn't jump all over the screen, and the learning curve to learn the different motions of using the trackball was about 10 minutes. I was quickly working through projects, presentations, and blasting terrorists in Rainbow Six 3. I would recommend this device to anyone who needs a new pointing device!
