Mine have been good also. I did break a temple hinge several years ago in Alaska but luckily it was covered under warranty.
If you're looking for good shades at a great price The Maddison River Fishing company is clearing out some discontinued Smith Action Optic polarized glasses.
Buy the photo chromic glass lens ones as the darken when it gets briter and are more scratch resistant than the polycarbonite lenses.
For $79 you can't go wrong.
I just bought a pair yesterday.
I see they are now sold out of the ones I purchased, so if you're interested I wouldn't wait.
Oh, I almost forgot, shipping was $8.95.
