I have a bunch of these laying around. I loose them all, buy some more, find some. Throw out the scratched ones, still haven't paid as much for expensive sunglasses that I always loose. Like the last pair that bounced off my face from a boat.  That was the last straw.  Expensive sunglasses just don't work for me. These do.  I can put them on top of my head without getting my hair caught in metal nose pads, too.  And my niece assumed they were Ray-Bans.
