These glasses are pretty good for the price.  They are polarized and they arrive with a protective case. The left lens was not completely inserted when I received them, but I never contacted the seller as I was able to pop it right in. I'm not sure how durable they are yet since I just recieved them. I may update later. One notable thing is that these fit a wide face. I usually fit too snugly in regular sunglasses and these are definitely a bit too large for my face. There's not much you can do about that so i'll probably leave them in my car for driving. Bottom line: if you have a big head, these glasses are for you!
