To all the haters: this mouse is actually pretty brilliant. Not only have I found the first mouse I (a giant man with giant hands) can palm grip 100% (and trust me, I've chewed through dozens of the things) but it is constructed really well and the software and sensor is powerful. It is a genuinely awesome product, and fairly underpriced for what you get. Even the soft touch coating is a fair few miles better than anything I've seen on other mice, just because my hands don't get sweaty when using it for hours and thus it doesn't get all stained and off-looking. (Though the coating transfers a mildly chemical smell to your hand)
For anyone with huge hands or long fingers, I can't imagine a better mouse for sale anywhere on the planet.
I also have Windows 8 and experienced none of the problems that a minority of users have had, but it should be noted that the first thing I do when installing Windows 7 or 8 is turn off every single anti-user's-happiness "feature" there is, like UAC, win defender/update/feedback, and also I take full ownership of the Windows folder and everything in it, and make myself permanent administrator of ALL THE THINGS.
