I love smith products and have rarely had problems with anything, however the Serpicos are below the norm of Smith quality. I'm on my second pair of these, and will soon be sending them back to Smith for warranty. The fit pretty good and look sweet however they fall apart. The metal on them is so pliable that regular use will bend the metal a bit. This results in the plastic lenses popping out of their frames. On both of my pairs this has happened, I think the metal is just too weak for a pair of sunglasses. I guess if these were only going to be used for driving, and stored in a hard case they might be fine. I would pass on the Serpicos for some other Smiths or some Ray Bans.
