This ergonomic mouse consists of a roller pad embedded in a broad wrist support. The pad also features a smart “touch-scroll” function. You can click anywhere on the roller pad.
Model: Mousetrapper Advance
The broad wrist support provides relief for neck, back and shoulders. The user gets a centered working position with hands close to the keyboard, mouse buttons and roller pad.
The user’s roller pad is somewhat to the left of the middle since she uses her left hand.

RollerMouse, Mousetrapper, Nomus, NC Mouse and Trackbal Emotion are all centered control devices. They help the user to achieve better ergonomics when operating the mouse because all repetitive work takes place within shoulder-width distance.
