The KidTRAC mouse has extra large buttons that are easy to find and click. The large, high-density ball and shape of the case act as a natural hand rest that mirrors the contour of the hand. Combined with the special "Ambidextrous" feature, the trackball accommodates both right and left-handed users and hands of all sizes. The color scheme is a bold combination of primary colors: blue, green, red, yellow, and white.
