Summary: The Ultimate Trackball
Review: I've no doubt about it, this is far and away the best trackball ever. I've been using it for over a year and it is SO comfortable; nothing else comes close. I want another.

Summary: Excellent but...
Review: It is extremely comfortable and actually fun to use. It would be the perfect input device if it only had a mousewheel. The button replacement is not nearly as good, but this is true on any device that tries to replace the wheel with a button.

Summary: Ultimate Luxury in Mouse Technology!
Review: Logitech has done it again. I have been a trackball junkie for as long as I've been using computers (which is 15+ years, I'm sorry to say) and the Trackman Marble FX is the ultimate luxury in mouse technology!There are many people who really dislike trackballs in leiu of standard mice, and for me, this is a plus! People tend to find another computer with a regular mouse rather than "borrowing" mine when they need to "just check my e-mail real quick." All my other trackballs would have to be taken apart on a regular basis to clean the little foam guides inside, but I have had my Marble F/X for over a year now and it is basically maintenance free. The red scrolling button is a fabulous feature and the mouse itself is very comfortable. Unfortunately, Logitech has not put this mouse out in a left-handed version, but for the majority of us who are right-handed, and especially for trackball aficionados, this one is the greatest! You will be very impressed!

Summary: No doubt. I love my Logitech Trackman Marble FX device...
Review: No doubt. I love my Logitech Trackman Marble FX device... and dread the day when it will no longer function. I do wish Logitech will once more come out with this device as it is or as a better, re-incarnated version.

Summary: Still Unrivalled as Best Trackball Device
Review: Once upon a time I got sick of the gunk build up on all the mice and trackballs I had used, it got to the point where they would bump and jump on the mouse pads. I was intrigued when I saw the technology used in the Trackman line, detecting position using the tiny dots on the ball. Now having used the FX Trackman at home and at work for over 3 years, I find that it is the still the best input device of its kind, including the new MSFT optical mice. Once one gets used to the button placement and develops the dexterity to utilise the trackball, constantly smooth and consistent movement will reward them. With no moving parts for the tracking assembly the user only rarely [once a year?] has to pop the ball out and clean the sensors. This trackball does very well in digital art work with Photoshop and is especially excellent when used to play classic trackball arcade games through Mame32 emulation, Missile Command, Tempest, Centipede, Arkanoid, etc. The tertiary buttons are recognized and used as scroll wheel counterparts in Win2k; it's a nice fluff feature. My only wish would be that Logitech eventually upgrade them to use USB so I can plug them into my MSFT keyboards. Otherwise, highly recommended.

Summary: great tool
Review: The marble allows precision tracking where desk space is limited, since it does not need any surface area to move around on. It takes a few days to get used to, but is a great alternative to conventional and optical mouse.

Summary: FX Handicaps
Review: The Trackman FX takes a while to get used to. Alternate users of your pc will have difficulty performing tasks. The only problem I have encounterd is with system upgrades. We are at W-2000NT and the upgrade software will not allow all 4 butons to be activated. I am using the FX as a standard PS2 mouse, but my carple-tunnel(?) has not returned.

Summary: Great Product
Review: This is a great product. I have had mine for about 2 years now and it is still as precise and smooth as ever. It is easy to clean and maintain and is great for graphic design. The only thing I have to mention is that this mouse is for right-handed users only. I do not believe that Logitech has manufactured a lefty version of this great mouse. Too bad.
