I am not a sunglasses snob. If you are, I don't know why you are looking at $4 sunglasses to begin with. For those of us who aren't, these do the job.  They have the same aviator look as more expensive pairs... they are just cheaper.

Maybe they aren't going to last forever. But so far they have been working fine after several uses.

If I had only one complaint (which I barely think can count against them at $4 a pair... after all, that's cheaper than ones you would find at Walmart), it's that they don't really stay up on my head when I put them up.  The sides don't have an extremely firm grip when they are loose on my head.  But they are great when they are on.

Recommend.
