The bottle opener hook is what sold them for me, as someone that prefers glass bottles over cans. They even reduce the time delay in replacement by mailing your new ones as soon as you send a photo of your receipt from the post-office.

Even tho they are supposedly made from aerospace grade titanium the frames are flimsy. The hinges become loose after a couple of months. These are not as strong as they advertise which is a bummer.

The sunglasses come with a life time warranty, but the customer service is terrible. It's a bit difficult to clean dust and other contaminant off the lens. I have several pairs of oakley's (all polarized) which i prefer over these.

Used their online chat and followed their instructions to send a pair back for exchange. They have an email address that comes inside the box that welcomes you to the william painter community and that is such a joke!
