KidTRAC has extra large buttons that are easy to find and click. The large, high density ball and the shape of the case act as a natural hand rest that mirrors the contour of the hand.
"Ambidextrous" feature accommodates both right and left handed users (without changing system settings) and hands of all sizes. No need to move your arm or rotate your wrist from side to side.
