The top answers sound like Oakley or Firmoo paid someone to concoct them, unfortunately a snake-oil style of selling that should be outlawed on the net.
Oakley sunglassess... I spent $250 for a pair of Square Wire's only to find out that they are defective and have an Oakley rating (customer rating) of 1.6- http://reviews.oakley.co%u2026. Of course, my glasses did the same thing and the right-side hinge busted just as I was ordering new lenses. They no longer make parts and have no empathy towards customers in this regard.
I expected Oakley sunglasses to at least work well for a few years for the price I paid, now I am very disappointed with the company and their "cool," but expensive and defective products (made in China?).
Always check the net, look at http://Amazon.com and check the prices and ratings. I called customer service only to be given a 35% discount on a new pair, and I could easily do better than that at Amazon.
Don't waste your money.
