The miniature case of the MicroTrac Ergonomic Trackball Mouse allows the user to hold the trackball in the palm of the hand minimizing fatigue. The MicroTrac also has rubberized feet allowing it to be used on the desktop like a regular trackball. It is Designed to easily accommodate both right and left hand users as well as different size hands. Using built-in dynamic motion enhancement, this miniature Trackball is engineered to give single-pixel control while still having the ability to move to the other side of the screen with a flick of the finger. Roll the ball faster and see the cursor speed across the screen, move the ball slowly and you get single pixel accuracy. This three button trackball requires no special drivers or software. Middle button acts as Drag-Lock and Scroll-Lock combination just like our most popular models. With the MicroTrac you can work precisely and comfortably for hours at a time. The Drag Lock feature makes this product more comfortable by eliminating the need to hold down a button to highlight or select items. Simply hit the Drag Lock Button and the button stays “locked” until hit a second time. Relax and cruise the internet with this small, unique pointing device. This trackball mouse will enhance any system.
