Evoluent VMCR VerticalMouse C Right-Handed Ergonomic USB Wired Mouse (Regular Size) - Perfect for Office Work, Graphic Design & Reducing Wrist Pain

First off, I have been using this mouse for autocad at work for over 2 years now and it is really a great mouse. Anyone who uses CAD knows that the number of clicks I've put on this thing is somewhere in the millions, but all buttons are still responsive and everything still works and feels like it should. The first knock I have on it is that it feels like a lightweight cheap piece of plastic and I was worried about this when I first got it. But I am pleasantly surprised at how well it has held up. The second knock is that after about a month of use, the wheel started to squeak and squeal like a worn out brake pad, but that went away after another 2 months or so and now it is smooth and quiet. I can't recommend this thing more and now my wrist doesn't feel sore after work.
