The Humanscale Switch Mouse (SMUSB). How much do you use your mouse? How much is your wrist and hand comfort worth to you? This ergonomic mouse is absolutely a must have for people with a need for an ergonomic mouse. It has the best ergonomic features and design in the mouse market! It's unique, ergonomic design puts the hand in the right position for long use, the whole hand rests on the mouse, so the user tends to use the arm, rather than the wrist to move the mouse. The expanding body allows one mouse to fit most hands, and it can be switched from right to left-handed quickly and easily! The Switch Mouse is an innovative mousing solution that boosts comfort and reduces the risk of injury. This groundbreaking peripheral device integrates two major innovations- a V-shaped base, which puts the wrist and forearm into a natural position, and size adjust ability to provide a perfect fit for any computer user. Other features include a built-in palm support to prevent contact stress on the wrist, four-way scrolling dish to minimize repetitive motion, and programmable buttons for user-specified functions. All of this adds up to the most customizable and ergonomic mouse ever created. Driver Download Instructions To install the driver, follow these steps: 1. Go to www.humanscale.com.
