I've been using the Trackman for over 16 years. Best marble mouse in the world. They do wear out eventually. This is my fourth one, and one of the previous ones only had to be replaced because of misuse and abuse by grandchild. I use mine at least  12 hours a day, 7 days a week. It *seems* like Logitech is going to discontinue this model and it is the only one that allows easy finger control instead of thumb.Tired of moving your hand to move your cursor?
Logitech has been making these for a long time - I had one of the older white ones with only two buttons, and I loved it. The design is attractive, ambidextrous, comfortable to operate, and gives precise fingertip control with a ball that glides effortlessly. It feels downright luxurious.The new model provide two additional buttons which are very useful if you can program and remap them. And there's the rub. . . The software included is very limited.
I bought this mouse to replace an older version of the same mouse. I had it for years, and it took a beating. When it did finally give out I didn't hesitate to buy a new one. I like being able to navigate with just a finger instead of having to move your whole hand, so it's a bit of a space saver too. The forward and back buttons are also great.
When I first got my package with the TrackMan Marble mouse inside, my first impression was that it looked MUCH bigger than it did here on Amazon. The whole reason I wanted to buy the TrackMan Wheel instead was the fact that its picture on Amazon made it look bigger, and that's what I was after.
i love it. why didnt i buy this long time ago. there arent that much choice for mac out there. this one you could customized left right, scroll up and down. usually with mac, you cant customized anything. but this one can. i wish they had it in a smaller model for people who have small hands. i dont miss the scrolling wheel at all. the best thing about this is that it saves my shoulder. usually you need your whole arm to move your mouse.
I had a older model for years and loved it. I just plain wore out the buttons on the old one and bought this brand new one. I love it even more as this one has the 2 extra little buttons for scrolling that my old one didn't. The old one I used on a regular computer where this new one I am using on a New Mac Mini.
I have been using Logitech trackballs since forever. In Oct 2012 I replaced a mouse that came with my new computer (Mac) with a new Logitech Marble. No problems...at first. For about 3 months everything worked as expected. In Dec 2012 the Logitech Marble I had been using for years on my Windows 7 PC started going out, or so I thought. I trashed it and replaced it with...you guessed it...another Logitech Marble.
I would recommend this product to everyone looking for a new mouse. It may not be the lowest price or wireless but it is worth its weight in gold. The sleek design that fits comfortably under your hand, conveniently placed center roller ball that allows you to not need a ton of rolling surface, and fair price  are just a few of the great features. I have been buying this model for years and usually buy more then one at a time because it seems to be getting harder to find.
I purchased this mouse for my Mac Book Pro because I can't stand the trackpad. I already use a Trackman Marble with my PC so I purchased one for my Mac. The drivers that come with the DVD are not compatible with Mac OS Lion but the latest Lion compatible drivers can be downloaded from the Logitech website. After installing the latest, I found configuring the buttons to be confusing but was finally able to configure the right button to be the primary button.
Answer: No all trackball marble mouses work just fine with the Mac.  I have two and I have the one in this picture.  I love them, once you get use to them they are so much more easier to move.  Enjoy
