How would you rate it?
I like it, the buttons all work and the mouse is fine. I wouldn't buy it now though, the software is crap, haven't gotten it working in windows 10, and there are much better mice out there for less price. This is "batman is cool" "I love gaming, I'm a gamer, I have money" bait more than it is an awesome mouse. I love the thing, and am using it now, but you can do better nowadays.
I did eight years with a Mouseman Wheel, ten years with an MX Revolution and I've had an MX Master since they came out, thereby crushing the formidable secondary market on used MX Revolution parts. If you're looking for a mouse, that form factor got me through four revs of AutoCAD, three revs of Logic and two revs of Pro Tools, 8-10 hours a day, for 19 years. No idea if it's any good for gaming.
