Logitech MX Vertical Wireless Mouse – Ergonomic Design Reduces Muscle Strain, Rechargeable, Graphite

My right thumb used to get sudden, stabbing pain where it joins the hand. I figured it was because I use a mouse all the time, right? After some research I learned it was probably the way I was gripping the mouse -- from above, pinching it between my thumb and pinky. It was obviously too small for my large hands and required me to make large movements from the thumb and wrist. First I cheaped out and tried one of those pads with a gel hump on one end. Nope. All it did was make my wrist hurt too. Next, the largest standard mouse I could find. Nope. I still pinched. Next, a vertical mouse. Better, but too small front to back so I still pinched. Finally I tried the Logitech MX. Outstanding. It could still be just a little longer but it's the best fitting mouse I've ever tried. Now my hand, wrist, and arm move together with minimal wrist or thumb movement. After 6 weeks the pain is almost gone, really more of a dull ache than the sudden stabs I got before. Note: Because my hand rides higher on the mouse now, there was a little pressure on my wrist from the edge of the desk. I got one of those tiny bean bags for the wrist with a zipper so you can add/remove beans to adjust support. The combination has really helped. So it reduced my pain but the MX is also a capable mouse. I use it for gaming and general office chores and love the way it works. I definitely don't need all those extra buttons that come on a dedicated gaming mouse to play my games, mainly WoW and D2R. I don't know about FPS twitch games or raiding though. If you know what that means you might need a mouse that looks like a stubbly porcupine. I'll leave that up to you. Highly recommended for anyone with mouse-related wrist or thumb pain, especially if you have large hands. To be honest I'd prefer this design even without the pain. It's that good.
