Yes, cosmetically nice. i.e. Not beat to shit. I don't need a new controller, but I don't want one that's cracked and looks like crap either.
Basically, you wouldn't look at it and say, "yikes". Now, Of course all the buttons need to work and the joystick should still perform properly. That's about it.
Doesn't need to be minty; just all original, all functional, and not jacked up.
