I'm almost positive these are fake! I have a pair I got from Nordstrom about 4 years ago. Unfortunately the arm broke off and I lost it.  I was finally able to make another investment and purchase these again because I loved them so much, and I was thrilled when I found them almost $100 cheaper on amazon. Even though there are some bad reviews, for the most part they are good. I purchased them and received them same day. I was sooo excited! Then I opened the box and immediately knew something was off. The creaking is horrible and they are definitely lighter than my other pair. The arms have a seam down the middle which my real pair does not have, and one arm doesn't touch when placed on a flat surface. It is the best knockoff I've ever seen, so I don't know whether to just keep them and save the $100 (because no one else will know) or send them back to get a real pair from SGH or Nordstrom. Someone had a good point in their review saying that RayBan backs up the authenticity of any glasses sold by Amazon and that they are an authorized dealer...but they might have found a way to make 2 different sets. The internet discounted ones and the high end brick and mortar sunglasses. China vs Italy... It's a shame. I was really looking forward to these and now I'm torn.
