This device has kept me working. I highly recommend it as a TOS friendly mouse, if there is such a thing. I would be out on disability if it were not for this. I got it when my ortho said he wanted my hands close to the body and just about at waist level. "Put them there and don't move them", he said.
This fits the bill pretty well. The ergo folks bought me one at work and I quickly bought one for myself at home.
Soon I will be adding Voice Activated Software to my arsenal...
