Got mine today. Mosts of the pictures I've seen don't do this button justice. It's kind of metallic red. Very hot and I'm stoked for the added HP.
Couple of comparison shots.
It "feels" better when you push it too. Maybe just because it's brand new and my other is 8 months+ old. Or maybe it is a Super Button from another planet, come to Earth to make our Zs even cooler.
