These glasses have held up for about a year of continual use. I keep them in the sunglasses holder in my car so that I can put them on while driving.

I have always been a fan of the full-mirror, and they look pretty stylish (the mirror looks like it is starting to wear off on mine).

I'm really bad about breaking sunglasses, so these were a cheap solution to an expensive problem. No more beating myself over the head over broken Oakleys or Ray-Bans!
