I got the Persol folding sunglasses and they seem to be authentic (which was a small concern given the low price) and I was very happy with them. I say WAS because I left them at the park on like the third day I had them! So mad but I'll be getting another pair from the site so I guess that is a review in itself.One thing is that I paid for 1-5 day shipping and I got them on the 6th day but other than that, great experience.
