I've had a set of these shades for about a year now... they are SICK. I have them in white/gold and am considering buying them in black/black. Haven't had any problems with anything on them, I've been hit by a car riding my road racing bike, they made it through almost untouched and perfectly intact, very durable, just take care of them. I got a pretty nice scratch in the lens from the accident but what would you expect out of any other pair of shades. Excellent protection from the sun, no complaints at all, whatsoever. Highly recommend to all those out there considering buying a pair/have the money to shell out, definately worth the investment.
