So i've been looking for a gaming mouse, that will also work on my Mac without much issue and picked up a Logitech G502. Ugh, I did not like that mouse all. The braiding on the cable was fraying out of the box, the scrolling felt cheap, and I felt the tracking was weird. So I returned it.
I know people swear by the DeathAdder, but I always hated the green, and they're kind of tacky, but Best Buy had the Chroma for $60 so I picked it up. Holy shit, its a night and day difference. It feels a lot more solid, the cable/braiding is higher quality, the tracking is smooth and it changes colors (though, I wish there was more control on the cycling setting). The only down side is I wish I could have just 1 more button for Mission Control, but whatever.
I was thinking about picking up the Logitech 302, but I'm really happy with this pick.
