I love the MJsports. I have them beside me right now.
I've actually lost two sets in a span of 4-5 years - one within a span of 2 months. (That really sucked.) I've occasionally had luck on Amazon with discounted pairs ($60-80) from time to time.
If I lose this pair, I'm switching over to a cheap set. Some people just aren't meant for sunglasses.
RE: I lost some expensive MAUI sunglasses.. what now?
