I've now purchased two pairs of these because I like them so much.

Pros:
-They're sturdier than others I've bought at similar price points
-The texture of the frames is like a matte finish vs. normal glossy plastic which is great because they don't look as cheap and don't get greasy when sunscreen gets too close
-They don't squeeze my head! Loose enough to be comfortable but tight enough to stay put
-They're dark enough to allow me not to squint in sunlight but light enough that it doesn't feel like evening when you wear them
-They come with a bag to keep them protected. And they're very affordable so even if they were scratched they could easily be replaced. I bought a second pair to keep in my car

Cons:
-The polarization is pretty weak. Normally with polarized glasses I can see into water when out on a boat on a sunny day, but with these you can't quite

UPDATE: I wore my second pair with sunscreen on in the pool and they gave me a pretty hilarious unibrow. They rubbed black on any part of my skin the glasses touched. I don't know if it was because of the sunscreen, the salt water pool chemicals, the hot weather or some combination. Just be aware, if people are giving you funny looks after you take them off, it could be that you've got sunglass residue on your face. My family got a good laugh.
