Excerpt: I was excited to find a 'joystick' mouse, to relieve my clicking-finger stress-even such a tiny movement repeated all day causes stress up to my shoulder. I hoped holding my hand in one place and moving it like a joystick would be different, but that's not how it works.
Summary: I get pains in my hands and knuckles when using a standard mouse and this is basically perfect for alleviating those pains. BUT - the scroll feature doesnt work with my Mac. Its maddening - an absolutely vital feature totally useless on my Mac.
Summary: I love my regular 3M wired ergonomic mouse (3M Ergonomic Mouse SMALL/MEDIUM), but because it's a bit of a pain to use a mouse that is tethered to the computer, I bought this wireless version and gave it a whirl.
Summary: I bought this mouse because i've been having a lot of pain. I work in spreadsheets and am using the mouse all day every day.
The product is comfortable but it takes me twice as long to get my work done. Within 2 weeks of owning the product, the buttons started giving out on me.
Summary: First, this mouse has two sizes. I am 5'8, male, and have average sized hands. The small/medium sized mouse was too small for my comfort. Second, I do not like having the main buttons on the top. Those who suffer from some type of RSI are generally susceptible to other types.
Summary: My hand was too big even for the LARGE version, which made my thumb rest in a very awkward position. While my forearm felt more relaxed using the mouse, my hand itself actually started hurting. Plus the drivers are old NT4.0 version drivers. They work with XP, but just barely.
Summary: I like the design of this mouse but after 5 minutes of using it, the scroll buttons started to stick and I realized I had to return it. Basically, the button is cheaply made and when pressed can slip under the casing, causing it to stick down and scroll like crazy. Hugely annoying.
Summary: Well, this is one of those things that ought to be a good idea, but it isn't in reality, the time taken to get used to it is also the time it takes to realize that its not really very good, the button on top (rocker switch between left and right mouse button) makes it impossible to use both together...
