  great for limited workspace August 26, 2008 This is the third of this "marble" mouse that I've purchased. I have all three on a desk with three PCs and five monitors. These roller-mice make-do with limited desk space---not enough room to slide around normal mice. I like the smooth tactile feel.
  Wish I'd gotten the thumb-ball one again August 23, 2008 I don't know what I was thinking... My previous mouse was the Logitech Optical Marble thumb mouse kind. It worked great up until it died (many years later). I saw this one and thought I'd give my hands a little change up or something, but I must have a stupid pointer finger that got used to using the rollie-scrollie wheel from the thumb trackball because I just cannot get used to this one (and I'm starting to hate it with a passion).
I use it on my Mac, and the only handy thing I've found--completely by accident--is that one of the buttons (the left tiny sliver one) works like the F9 key, reducing and showing all the windows on my desktop. I miss the scrollie wheel, I continually accidentally click the right buttons in some right-clicking fashion, stop, unclick, roll pointer back to what I was really doing, curse the mouse, go do something else. I'm sure I could program them all to do something else more useful, but the other one was SOOOOO easy and comfortable just like it was. I also find that I must have some ridiculously heavy thumb since I am always clicking on something that I don't want to select. I'm not sure why the track ball is much bigger on this one versus the thumb one--feels like my pointer finger is pushed up too high, waving around in space.
I've really given this a good try now and, I think I'm going to order the thumb version (and find someone who wants this one). I just don't like the way my hand "drapes" on this version--it's not comfortable, not as intuitive, and much harder to use.
  Not fully Mac compatible August 19, 2008 THE UP AND DOWN SCROLL BUTTONS DO NOT WORK WITH MY MAC (OS 10.5), and since the driver CD-ROM is FOR WINDOWS ONLY, I can't do anything about it. With this thing I have to mouse over to the scroll bar and click + drag up and down, which is a stupid hassle. If I'd known that I wouldn't have bought it. (It's too inexpensive to return.) To say that it's Mac compatible is false advertising. On the up side, if I had a PC, I'd probably be satisfied.
  Sticky ball is aggrivating: design flaw August 15, 2008 I really like this mouse than any other I've used. I write and do internet research all day long, and this has eliminated wrist pain caused by a traditional mouse. I have been using it for two years.
However...
From the get go, the trackball rolls a bit rough and has consistent stiction that is really irritating. I have tried cleaning, replacing with a new one, to no avail. Now looking for one that rolls more smoothly.
  Helped Me Eliminate Carple Tunnel Discomfort August 6, 2008 I purchased this mouse to help reduce the carple tunnel discomfort I was experiencing. After 2 1/2 years of use it has been very successful for this purpose and my carple tunnel discomfort has all but disappeared. My strategy has been to have a regular mouse and the marble mouse connected to my computer at the same time; and then to switch around from left hand marble mouse usage to right hand marble mouse usage to right hand regular mouse usage, a few times during every hour of computer usage. The marble mouse makes this easy since it can be used with either hand. I also have found it very comfortable to use the marble mouse in my lap.
