Mmmm may want to look at after sales support here. I have 3 pairs of Oakleys and their support has been great. I broke the frames on all three and they replaced them free of charge. In fact my Zeros were replaced altogether, frame and lenses.
Also the lenses are brilliant. I had an opertunity to whack a lens with a hammer last weekend and there was just a small scratch where the hammer connected. Beleive me I hit it pretty hard.
I have also had the "pleasure" of testing a stone shot up from a car as I was speeding down a hill at around 60 - 70 kph. I saw this stone get thrown up from a passing car wheel. But I reacted a bit too slow and the stone bounced off my glasses. A small mark was left where the stone hit the lens but I can live with that knowing that I can still see.
This is enough proof to convince me that they are the best glasses around.
