"Science-Driven Design.
The Delton Ergonomic 12 Vertical Wireless 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 a long-lasting battery that will keep your Delton Ergonomic 12 Vertical Wireless Mouse powered up to 30 days of daily use and as much as 12 months standby time with just 2 AA batteries.

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.
