10 stars for customer service. Purchased these a while back and absolutely LOVE them.  Unfortunately, the frame cracked recently, but I contacted customer service and within a week of my sending photos of the damaged frame I had a new replacement pair in hand.  In between, I had to break out one of my other pairs of sunglasses and never realized just how much better the lenses protected my eyes with these Duco shades.  I like to change things up and and will buy Duco brands when I do decide to get a different style.
