As some reviews have pointed out, these are not the most quality glasses. However, my 4 star rating is based off of cost vs performance/style. They're $12 and for good reason, there are no bells or whistles (hell, a bell and a whistle on sunglasses might be the next big thing, eh?). You get what you see, so if you're looking for a good looking pair of shades that you couldn't care less about losing, hop on these! They look almost as good as their $150 counterparts. Be sure to add another $38 worth of goods to get hooked up on free shipping and make the purchase worth it!
