Unusual, joystick-like design reduces forearm twisting; available in two sizes; inexpensive; includes PS/2 adapter.

Buttons not programmable; no left-handed version available.

The 3M EM500 Ergonomic Mouse requires some adaptation, and it offers only the most basic mouse functionality. But the payoff is a more comfortable mousing experience.

Eased the pressure I was feeling in my wrist and elbow almost immeadately.

Although relatively easy to work out, beter instructions on use of "scroll" button would be beneficial

Stops RSI.

Expensive.

It does seem to have helped with the RSI i have been having through over excessive mouse use at work. I can use this all day without really aching yet if i use a normal mouse my hand aches within a short period of time.

It takes a bit of getting used to. On the first day i went home with hand, arm and shoulder ache because of using different muscles. The advice in the box is spot on though it does say it will take 2-3 weeks to get used to it and it does! The other...

I'm heartbroken that Newegg only allows me such a limited space to voice my love of this mouse. For almost two decades I've suffered from chronic pain and discomfort in joints throughout my right arm. I've tried nearly every form of "ergonomic" mouse...

It will save your wrists from carpal tunnel, no more tingle

not cheap

Cold painful hand from repetitive stress injury is gone. Comfortable, easy to get used to (for me anyway)

I would have given this thing 5 eggs if it had a scroll wheel, some applications just don't work with just a third button, rather annoying really ; Nothing to do with Newegg

I have digital tendon entrapment syndrome (also called "trigger finger"), which is like CTS, but the restriction is in my palm, not wrist. This is the only mouse I've found, that doesn't require anything from your index finger. The weight of your arm...

I've you've got dozens of brand new mouses sitting in a desk drawer, and have paid $500 for cortisone injections, so I would have gladly paid an extra $10 for a little better quality

Seems to work as advertised

The description on NewEgg didn't explain that there is a difference between the two models listed. I should have figured it out, but must have been having a dim day ; The "L" Model is large, for people with hands 3.5-4" across he nuckles. The "S" model...
