The Pro Fit Ergo trackball is suitable for use in confined spaces such as in a cafe, at the kitchen table, on a train or on a plane. “It impressively meets the need for a handy and ergonomic input device that can be used anywhere,” the jury found. Its shape adapts to the natural curvature of the hand, so it can be used comfortably for a whole day without putting too much strain on the wrist and forearm. The natural hand position combined with the familiar button layout of a mouse and a 4D scroll wheel also increases productivity and provides a smooth user experience.
