basic mice

I felt the difference in my right wrist instantly. According to websites, "Ergonomic design keeps the arm positioned for natural, comfortable movement. It is clinically proven to reduce muscle strain and discomfort associated with Carpal Tunnel Syndrome and repetitive stress injury. The 3M Ergonomic Mouse is compatible using any USB port computer."

Ever notice that Gamers don't have carpel tunnel syndrome like most typists even though they likely spend more time at the computer? Well, 3M noticed! Your wrist sits on this ergonomic mouse like it does on a video game joystick. The weight of your hand is no longer carried by your wrist. Rather, your hand is relaxed on the mouse.

The relief in pressure on your wrist is instant. The cost may seem high, but it's less than a chiropractic appointment. Comes in 2 different sizes (small/medium and medium/large). This is a RIGHT handed mouse. You can program the left/right clicks if you are left handed, but the "joystick" is angled, so it's not as wonderful if you are a lefty.
