I purchased a pair of Costa sunglasses for $225. The are supposedly guaranteed for life. After a few months the metal wire that connects the frames near the nose piece separated from the rest of the wire frame. The tiny weld broke loose. I sent them to Costa for repair and they said it was damage done by me because I shipped them in a hard glasses case that fit the Costas too snugly in their opinion. Ridiculous! If the wire frame was not already broken there would have been no need to put them in that case and ship them in the first place. These guys are cheats and frauds. You can get better glasses at Walgreens for $25.
