The R-Go HE Basic mouse features an ergonomic vertical design that promotes a natural, relaxed posture for your arm and hand. This 'thumb up' position encourages larger, healthier movements from the arm rather than small, potentially strain-inducing movements from the wrist, helping to alleviate pressure on small muscles and tendons and prevent conditions like RSI. The mouse is intentionally lightweight, requiring less muscle tension for operation. Its rounded design offers optimal hand support with a natural grip, including dedicated support surfaces for the thumb and little finger.
