X-keys O-Trac Primary Trackball

White bodied USB Opto-Mechanical Trackball with multi-coloured buttons and the yellow globe.

The large, high-density ball and shape of the PC-Trac case act as a natural hand rest that mirrors the contour of the hand. Combined with the special "Ambidextrous" feature, the PC-Trac trackball accommodates both right and left-handed users and hands of all sizes. No need to move your arm or rotate your wrist from side to side.  You will enjoy this desktop trackball's ability to dynamically accelerate across the screen as you turn the ball faster!

Made in America with only the highest quality components and materials, X-keys (formerly produced by Clearly Superior trackballs and known as the CST-1350.) have a reputation for reliability and performance. The large precision-ground ball and mirror-finished rollers deliver a "smooth-as-silk" feel and effortless control

These easy to use, large trackballs are well suited for those with disabilities and physical handicaps.  CST also offers "switch adapted" trackball models that allow the use of external switches for persons with motor control disabilities.
