Summary: I'm a big fan of trackball mice and have owned a few different models and this one is a very solid option if you don't want to dish out a lot of money for the high end ones.
Pros: I have been using this mouse for more then 4 years and it is still very responsive. Usually the ball on the mouse would not roll smoothly after as much use as I have put on this one. It's long design fits my hand very well. Good support for the inside of my palm
Cons: Limited Features and the two secondary buttons are not placed well.
Summary: I have a newer model marble mouse but my teenage son was a bit rough with one of the buttons and it double clicks for every single click. This was a decent replacement for a product that new is still running at $30.
Summary: Have not used a regular mouse in over 10 years. First logitech trackball I had was a Marble FX Optical Wireless, unfortunately they don't make those anymore. Having used a trckpad for a couple of years, I get cramped fingers and was ready for a trackball again.
Pros: Having fairly large hands, it still feels quite fitting. If you have really large hands, this one might not be fore you. Software is very useful and buttons can be programmed to do anything you want. The best thing this does is force your wrist not to lay flat, but more into a (near) handshake po...
Cons: No scrollwheel, of-course knew that when buying. Wish the scroll ball was somewhat larger for more precision. Small buttons are hard to get to.
Excerpt: I've used this mouse for 5 days and am sufficiently pleased with its performance. Not ideal for twitch gaming but otherwise very precise. I picked the marble because I wanted something that didn't need any real estate to move around.
Excerpt: ThisTrackMan is easy to use. The keys are programmable which saves steps, and it can be used with either hand or switched back and forth between hands. I've had mine for several years, and am buying another for my other computer.
Summary: I love this trackball. I am a 'gamer' and ever since i first got this particular model of Trackball, It is the only one i ever use for FPS games. Its so much easier to use this than a normal 'mouse' or even other track-balls which have the 'ball' were your thumb would rest.
Pros: Easy to hold. doesn't move around a lot when your using it, and buttons are easily reached. Vary easy to clean.
Cons: Buttons (left and right mouse buttons) tend to wear out quickly. Fingers are 'slightly' arched when using. (the ones that rest on the ball, would be nice it if sat a little 'lower', but this might mean having to make the rest of the mouse 'taller' to do. Not a big con, just one that comes to mind.
Pros: Really great alternative to a mouse. Drivers work every time on Windows start up. Scrolling feature is faster and smoother than scroll wheels I've used. Basically, unless you're on a Linux system there are no cons IMHO. Even dropped it a few times and the ball stayed in place.
Cons: Hit and miss with Linux installations. Works great at first but not so great after restarting the system. You can find the Linux drivers by entering these commands in a Linux command prompt.. sudo apt-get install gpointing-device-settings sudo apt-get install libgpds0 Some programs on Windows and...
Excerpt: I work and play alot on my PC - I know this TrackMan Marble Mouse will save my hand and wrist a lot of wear and tear. I wore my old one out after more that 6 years. Glad to be able to still buy one.
Pros: Ergonomic Layout, Fast Response, Smooth Movement, Space Saver Wrist Saver
