Basically a wireless G403 - meaning it fits best for larger sized hands, favoring palm and claw grippers. I personally don't like it that much because the hump of the mouse is a little too backwards which feels awkward for my palm - this indicates that my hand simply isn't big enough for the mouse.

If you have a G403 and you don't paracord it, you aren't doing it right. The G403's stock cable just suck balls and it was the first thing I did out of the box was to paracord it.
