There is no need to adapt to a radically new mouse orientation to gain ergonomic benefits. Unlike mice and joysticks that require a completely vertical orientation of the hand, the Goldtouch Ergonomic mouse positions the hand and wrist in a naturally sloping angle. The user is immediately oriented to the shape and angle of the mouse, and is therefore, immediately productive.
