Why do you think a computer mouse has such an unusual name as "marble mouse"? Well, the answer is in front of you. literally. Just take a look at the picture of this mouse and you will know why. The trackball attached to this mouse is nice and shiny and red just like a marble.



Besides, the main purpose of this kind of mouse is the increased sensitivity and accuracy that you need when you are working with such software applications like Photoshop or when you need them in special games with such requirements for getting good scores.

Trackballs are also very good ergonomic devices as they help you avoid repetitive strain injuries. Normal computer mice might cause this because you use your fingers to make almost the same repetitive moves for a long time. But when you are using the Logitech Marble mouse you don't have to click a lot, as you only rotate the trackball and this way operate the mouse and move the cursor.

Unlike normal computer mice that might not work on certain surfaces because they are too shiny or reflective and dissipate the mouse's signal, the trackball mouse does not even have to move. The only part that is moving is the trackball. It is fixed in a solid support that looks like Teflon and it moves very smoothly. That is the reason why this computer mouse is preferred in the offices where you don't have too much mousing space, so you don't have to move the mouse.

This Logitech Marble mouse has optical sensors detecting the position of the trackball and this determines the cursor's movement on the computer screen. As opposed to other computer mice, this one has the buttons on the sides: two big buttons and two small ones, rather included in the case and somewhat protected by the two big buttons.

The big side buttons are used for the usual click business, left and right click, and the two smaller ones are used for scrolling. However, all the four of them can be programmed to performed whatever function or operation you might think necessary, like opening applications, folders, shut down, volume control and whatever you might think of.

This mouse is corded, so it can be connected to the USB or PS2 port of your computer mouse and does not need any additional software unless you want to re-programme the buttons' functions and change their default settings. The Marble mouse is also very good for those users who have some problems moving their fingers or squeezing their hands.

These computer mice are strongly recommended for people with carpal tunnel syndrome, RSI or other hands and fingers conditions and the results are spectacular, as you don't need any kind of force in your fingers, tendons or wrist in order to operate this mouse. Kids seem also to handle this kind of mouse a lot easier and better than other mice.Besides, the unique and original shape allows both right handed and left handed people to use it safely.
