ok I usually dont add my two cents but I dont want this to happen to you....I bought 2 pairs of gascans 1 white 1 black.  I thought it was a great deal like a lot of items on ebay.  I recieved the items.  Wore them and they litterally hurt my head.  I had an ex oakley rep even look at them.  He was also convinced they were real..I did more research and googled fake oakleys.  It had a link to a Wee Lee who said Fake Oakleys 12 pr for $220. He added GOO fo Ebay.....with black and white  gascans with box and warrentee.  So here is what you do.  First ask for a reciept for the glasses. Tell them you want it for warrentee purposes.  They cant provide it.  also take the glasses to a real dealer and compare.  The hindges on the fake gascans are different.  So be ware.....just because it is GOO fo ebay does not mean its Goo fo you.........Bonzothecat
