– The Accuratus Upright Mouse 2 is designed so that your arm is straight and wrist is in a natural position, allowing very comfortable use when working on a computer, a great help for users with arm, wrist and shoulder problems. As more and more of us find ourselves glued to a desk for 8 hours or more each day, it’s not surprising that an increasing number of us are showing symptoms of RI (Repetitive Strain Injury) and aggravating hand and wrist pain such as Carpal Tunnel Syndrome, two disorders that can be severely aggravated by a poorly laid out work station and the type of mouse pad. The Accuratus Upright Mouse can make dramatic improvements and ease painful or problematic symptoms in your hand, arm and shoulder. The mouse fits comfortably in your palm in an upright position and keeps the bones in your arm straight, eliminating the uncomfortable twisted position caused by standard mice. All the usual buttons are there, including a left/right click, and a scroll wheel of easy navigation of the internet and all your documents. The Upright Mouse 2 offers a far sleeker and modern design compared to our original Upright Mouse. – RF 2.4Ghz Wireless with 10 Metre Range via USB Nano Receiver – Silver with soft black tactile rubberised surround – Helps with prevention of RSI and Carpal Tunnel syndrome – High resolution 1600dpi optical sensor – 3 Responsive tactile feed-back buttons including scroll wheel – Works using 2 x AAA batteries (not included)
