Right handed? Left handed? Either way, TrackMan Marble’s ambidextrous design and large fingertip-controlled trackball give you fast, smooth accurate cursor control?without moving or straining your hand and wrist.

The long, broad palm area and gentle contoured shape provide maximum support and comfort for either hand?ideal for anyone who spends long hours working at the computer.

Two control buttons make it faster and easier to move forward and backward when you’re surfing the Web. (Requires Windows-based PC)

You’ll enjoy fast, accurate cursor movement with just a move of your finger.

Logitech’s patented sensor technology gives you smooth tracking on almost any surface so you can be productive wherever you work. (Does not work on clear glass or mirrors)

The stay-put base keeps your trackball?and your hand?in one place, helping reduce wrist fatigue. Plus it saves desk space since you don’t need room to move TrackMan Marble around to move the cursor.

The larger trackball makes it easier to control the cursor with less movement of your hand, delivering a great combination of all-day comfort and precision.
