These are my favorite thing I own. I am not exaggerating - I get so much delight from these sunglasses and think they are the perfect product. Things I love: - portability: so small I truly can take them anywhere, so my eyes are always protected. - look: best-looking sunglasses I've ever owned and I feel instantly cooler wearing them. - durability: I've had mine for three years now and only recently scratched a lens, which was my own fault for leaving them on some rocks when I went swimming rather than putting them in their case. The fact that they stayed spotless and non-broken until now is a miracle considering how much I wear them. - weight: I love how light they are. I often wear them playing sports (volleyball, running, tennis) and they never feel like they're going to come off. - protection: the polarized lenses feel like they really shield my eyes, and the lenses are high quality so I can see everything I want to.
