My initial order was delivered quickly, but I complained about the poor fit and the weird beveled edge they had put on the lenses. What they did is to bevel the edges at an angle along the eye-sight line rather than at 90 degrees to the lens. I assume the theory is that it makes the lens edge less visible to the wearer. Unfortunately they also finish the edge in a milky-white matte finish. Combined with the angle of the edge, it makes it appear that you have a distinct thick white ring around your lenses when viewed from the front. It's especially visible if you have a high prescription (thick lenses) and wire-rim frames. It's ugly and distracting. I've never seen that before on any glasses, including previous ones from G4U, but their comment back to me was that person responsible for lens grinding does whatever they think is appropriate, and there's no guarantee what sort of lens edge I would get from them in future. They were willing to send me a replacement pair of glasses for free, but recommended that I select only full plastic frame glasses so that it would help cover the lens edge. I don't like plastic frame glasses, but given that they wouldn't guarantee to finish the lens edges any differently, I felt I had no choice.
I have now received the replacement glasses. It took some time going back and forth with G4U customer service to reach a conclusion, but the glasses themselves were finished and shipped as quickly as the first pair. The lens edges are indeed finished exactly the same inappropriate way as the first pair. That's why I won't be ordering from G4U again, since they seem unresponsive to customer feedback on this issue. The glasses themselves are ok for plastic frames, but give the impression of being very cheaply made.
