Delicate, but the best shades I've ever owned
I've had these for almost 3 years and wear them everywhere. They're by far the lightest, most comfortable sunglasses I've ever owned, and have excellent coverage and optics.
I did have an issue where the bridge broke on my first pair, but the folks at MJ were super nice and repaired them for the cost of shipping. I was under warrant at that point but apparently you can get these repaired for a minimal fee even after the warranty expires.
Since they broke I've been more careful, as you probably should be with shades that cost this much, and haven't had any problems in the 2+ years since then.
