P.S.: Makes a great, modern tech present! 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 ergonomic 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! Note: This ergonomic mouse is far different than any other- pay attention to the detail! Also, programmable driver only for PC's. Mac driver to come soon, but it still works on a Mac. 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 prosition for left or right-handed users, and size adjustability 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.

The rep brought the sample in and I was immediately impressed. Not only can the mouse be adjusted in length, but the palm of the hand rests comfortably on the back of the mouse, so there's no dragging of the hand on the mousepad or desktop! A very comfortable, easy to use and highly adjustable must have item for anyone interested in ergonomics! As soon as these puppies ship, I'm getting one! One note, they do take some getting used to... they don't act like 'traditional' mice.... One more note: Since I've used mine, the pain in the wrist I was developing has now mostly disappeared! It really does work!
