I love these shades for a stylish set of shades. The only thing I can knock on them is the screws tend to get loose, & lens will pop out if you don't watch it. This has happened to me twice, sent them back to Smith & each time I get a new set of Serpico sunglasses. Considering I got them for 50% off back in 2009, I've got good value out them.
If you have to pay retail, buy Smith, the warranty last for lifetime!!!! I know people who have sat on their Smith sunglasses by accident, shattering them & got a replacement set for free. I wish more companies were like Smith Optics.
