I generally do not spend more than 15 bucks or so on sunglasses. Between the breaking, losing etc., it just makes me feel a lot better buying cheaper ones. That being said I am used to pretty low quality shades. These glasses, however, are very reasonable in price and they are really nice.
Pros
-they have a solid construction
-fit well and cover the sides even though they have an aviator style

Con
-my only issue is that the color of the lense tint is a little more feminine that I like.  Not too much to stop me from wearing them, but more than I prefer. I guess that is the style these days.

Worth every penny
