Four of the five glasses were - especially for the price - fully in order, only at a (Aviators in silver), the glasses were different dark. Have complained and got immediately a personal mail (no standard Ctrl-C Ctrl-v-mail) with apology and the assurance of a free forwarding a flawless copy.
So then was it, and I do not even have to return the other glasses.
Little lack so, but because of the customer service still 5 stars!
