I do not wear glasses, so I have no opinion on the company. I like the low price, my sister just paid $400 for her glasses (in Canada, where everything is overpriced), and the whole buy 5- keep one model sounds like a great fix to online shopping problems.
Edit: My favourite version is the "Crane" model.
@monetarydread: Yea, I payed about $400 for my current 'Guess' pair. Texas. I have shitty pretty-fucking-bad eyesight, and a bit of astigmatism. So the lenses usually cost a little more, and come in a bit thicker.
But 'Crane,' eh?. I do like me some 'brown' color. Thanks!
Hipsters wear flannel and knitted caps when they're not cold, tight jeans while not riding, canvas shoes in the rain, sunglasses when it's dark, and regular glasses without lenses. If you wear glasses because you need them, it doesn't matter what they look like: you're legitimate.
