Delton Ergonomic 12 Vertical Mouse - USB

"Science-Driven Design. The Delton Ergonomic 12 Vertical Mouse combines ergonomic comfort with common sense productivity to deliver high-end performance. Based on the 10+ years of feedback we've gotten from you, each Delton Ergonomic 12 mouse is made soft-to-the-touch and easy to manipulate on nearly any surface. Take advantage of intuitive controls, easy to adjust precision, and rheumatologist approved design to be more productive without the added stress and strain on your body that comes with traditional mouse usage. Comfortable & Healthy Our goal is to get your hand to rest in a natural hand-shake position. The unique vertical design of the Delton Ergonomic 12 series protects your health by reducing pressure on joints and preventing injury during prolonged mouse use. Traditional mice require your palm to face down, this forces arm pronation (crossing of arm bones), and strains your wrist. The Delton Ergonomic 12 series, on the other hand, is optimized for ideal hand posture that not only protects you from injury but also reduces hand fatigue.
