Summary: Simply the best!
Review: In working at a computer store, I try out all kinds of mice everyday. There is only one pointing device I use on my personal systems.. the Logitech Trackman Marble. I purchased my first one about 2 1/2 years ago, and now own 4 of them. Takes about 2 days to get used to, but once you do, you will not want to go back to a regular mouse.

Review: It sets the standard. I cut my computer teeth on a trackball and anything else is just plain cumbersome. You can't imagine how much more control and speed you'll have with this gem. Its just so much easier to direct precise movements with your thumb then with your whole hand. Give it a try, you won't be sorry.

Review: Once you go track, you never go back. Accurate, fast, and comfortable, Logitech's TrackMan Marble Wheel is a great example of quality design and manufacturing. If you are looking for a device that will allow you to work faster and longer in all of your applications, you've come to right place.

Summary: Nowhere near as good as the original.
Review: The ball is sticky and doesn't move smoothly. I had the non-wheel version for years and it still operates better. So far it appears that Logitech's tech support is pretty weak - it asks a lot of questions but they close the case without providing an answer. To follow up you then have to re-enter all of your data.

Summary: Excellent mouse, but can cause compatibility problems.
Review: The Trackman Marble Wheel is one of the smoothest mice on the market. It boasts a very stable configuration, placing the marble under the thumb and allowing the fingers to operate the buttons. This eliminates the annoying skate problem so prevalent in thumb-button configured mice.This unit features the standard left and right button structure, with a third button in the center containing a scroll wheel. The wheel provides normal vertical scrolling, but can be programmed to provide horizontal scrolling, zooming or a number of internet or Micro-Soft application specific functions. Additionally, by pushing the wheel straight down, you activate the auto-scroll or scroll-lock function, which then allows you to scroll over a 360 degree area, following the cursor as directed by the marble. There is one significant drawback to this unit. In the words of one Logitech support technician, the operating software is "very particular" in that it is not compatible with other mice. In order to get the Trackman Marble Wheel to function properly, you may have to completely uninstall any existing mouse and its associated drivers. This may create a problem if other members of the household prefer a different style of mouse. Overall, the Trackman Marble Wheel is an excellent device, and the price asked here is a genuine bargain. The combination makes one of the best values in the computer peripheral market.

Summary: Wonderful
Review: This is a great input device. I have a cramped desktop and no room to mess around with a mouse and mousepad. The TrackMan takes care of that problem. It is easy to operate and the software was easy to install and run. There are a lot of extra features that the middle wheel can do. It works as a butoon and a wheel for scrolling making scrolling through documents or webpages much easier and quicker and the price is unbeatable!

Summary: Silky-smooth pinpoint positioning from a stationary platform
Review: This is my second Logitech trackball. The first gave me four years of heavy use before the ball became sluggish and the left button, the main button, got cranky, wouldn't click predictably. Well, everything with moving parts finally wears out. (The regular cleaning this device requires, like the ball in a conventional mouse, no longer responded.) My first use of the new one was like pulling out in a new Mercedes. The ball responds to the slightest touch -- a most delicate resistance provides precise accuracy of movement. The buttons on the new one have something the old version didn't have, positive tactile clicks. I don't understand those who have trouble training the thumb. It is, after all, the second most agile digit on the hand. Thirty minutes and you're proficient with the ball. A slight flick of the thumb sends the pointer clear across the screen. Another complaint I can't understand concerns delicate pointer positioning with the roller ball. The thumb can provide much more precise movement than the hand holding a conventional mouse. I often work with graphics, following irregular lines. The conventional mouse gave me a lot of trouble. Not this one. I can trace the most delicate pattern with ease. As for zeroing in on radio buttons -- Good grief! Nothing to it.... Anyone who gives this mouse a try will love it. You'll not miss running off the mouse pad, having to pick the mouse up and "return to start" to get back on course. All the wrist movement will be a thing of the past. You won't have to push papers out of the way now and then to maintain the airfield a regular mouse demands. Just yesterday I worked on a friend's computer and was cussing his old-timey mouse, wondering why users put up with them. I secure my TrackMan to the desk with a little patch of Velcro. If I don't like the position I can change it. Once set, your hand falls on it in precisely the same way every time. As for that wheel ... well, I can scroll with scroll bars better, and I don't need the Internet menu that is provided as the default click. (It can be programmed to do other things, so you might find a use for it.) It does have a function for me -- a nice little ridge that seperates left and right buttons. Someone below reminds us that all other mouse software (even Logitech) must be removed before installing the Logitech software, and that should be done. Do it through the formal uninstall process (My Computer, Control Panel, Add/Remove Programs, Restart). And remember, since you won't have a mouse during the short installation process, that Control-Escape brings up the Start Menu, arrow keys move you around in it. The Enter key will activate default buttons and Alt-(letter) the others. We only use two devices to operate these incredible machines -- keyboard and mouse. If you take my advice and get this mouse, you'll be at home with it in no time, wishing you'd made the change sooner. As for keyboards, I had the Microsoft Natural Keyboard a year before I gave it a try. Voila, another one-hour period of adjustment. I was right at home with it in a few days. Now I HATE the conventional one. The above from a guy that uses a computer and a variety of fairly sophisticated programs all day every day.

Summary: An excellent and comfortable trackball.
Review: This is my second Logitech TrackMan, the other being the "TrackMan Marble +". I decided to test this unit by hooking it up to a laptop via USB and to use the native Windows 98 drivers. The "plug and play" worked without incident. Although I don't have the degree of function control I would have with the Logitech software, the TrackMan works; and I believe the computer is less prone to lockups and crashes without the "Mouseware" installed. I found the thumb marble easy to adapt to. The only thing I could wish for is the more precise cursor control offered by the TrackMan F/X (which Logitech says is not forthcoming in a USB version). If you're like me and prefer the feel of a trackball to a mouse or have limited desktop real estate, give the "TrackMan Marble Wheel" a try. You should be pleased.
