Title: I stand behind it!
Review: It is absolutely better for you than a traditional mouse! It may take a small period of adjusting for some, but many will take to it right away. Some reviews say it can stress the user's upper arm/shoulder, so be sure to adjust your seating position and keep your elbow in close to your body while using it for long periods. The 3 buttons work on the Mac, but only as a left, middle, and right click -- the programability and scrolling features don't work on Mac platforms. This is the ONLY reason why I didn't give it that fifth star! It's light, it's smooth, and it's very ergo.
