The seller, Shadesdaddy, did a great job with my shipment. They came in the original case, inside the original box, wrapped in bubble wrap in another box, I feel there was no possible risk to glasses getting damaged when shipped.They were authentic and brand new, for way way under retail. I was near buying this exact same model in store and backed out because of price, but I feel that at 1/3 of retail the value was very good.Lastly, the actual glasses are pretty great. The lenses are phenomenal, I would compare them to old Ray-ban glass lenses for clarity (superb) and the polarization and tint is really nice for driving or dealing with reflections off the water. The only complaint I have so far is the rubberization on the temple tips makes them a bit thick and can wear on my ear after a few hour drive. I've adjusted them and think I've solved this issue for myself.Overall, I'm really impressed by Costa Del Mar quality, its there with any other high-end brand such as Ray-ban, Oakley, or Maui-Jim, with their own unique styling, and definitely durable. Look forward to many years of use.
