Last night was the first time in 2 years, where I could bust ass in Maya, with ZERO pain or tingling sensations in my forearm. Been using the Evoluent Verticle Mouse for about 2 weeks now. It took me about 4-5 days before I felt like my speed an accuracy were up to where it was with a traditional mouse. However, it felt comfortable the very first time I relaxed my hand on it. One thing they fail to mention on the website is how your wrist is less restricted when flapping, instead of trying to move side to side. This is a BIG factor in it’s comfortable use. Because I’m able to swing my arm around more comfortably, I’ve lowered the mouse speed so it’s not as sensitive. On a traditional mouse, I usually work with a pretty high sensitivity, to limit my wrist’s side to side motion.
The Evoluent V3 has just come out.
* UPDATE *
It’s been over a year now and I still use the Evoluent. I’m still a fan and I’ve seen a few popping up around the studio as well. When I’m forced to use a normal mouse, I shiver.
