When I opened the package fell to me first a loose screw, a nut and 2 Plastikbeilagscheiben on the floor. At first I wanted to send the glasses right back, but then I thought to myself, I pull the screw on easily and does not have a few more days to wait for new glasses. So I searched the carpet, put a pair of tweezers, assembled and placed the thing. Unfortunately, I have a fairly broad head, so it was a little too tight. So I tried the glasses around the nose bridge a bit cautious and aufzubiegen * barney * is already a spectacle lens to another screw broken. Well, even so nothing more in debt to return to, but the quality of the glasses deserves in my opinion anyway no more than one star. 1st and 2nd defect arrived very fragile glasses. Since I already had sunglasses from the same price range that were much more stable and arrived safely in particular.
