I'm off to Ecuador for three months soon and need a pair of cheap sunglasses to take with me. Just for a crack I bought these as I've always fancied a pair of aviators. Unlike with some previous reviewers, they arrived in a cardboard sleeve rather than a padded envelope so were well protected in transit. Admittedly I thought they might look a bit tacky, but they don't... they look the bee's knees! They're comfortable to wear and required only a tiny bit of bending to fit perfectly. Well worth the price, in my opinion.
It's worth noting that the lenses aren't plain black, they are slightly mirrored. Not perfect silver like some aviators, but mirrored enough to hide your eyes and for people to be able to admire themselves in them.
