When I was choosing a new eyeglasses, I tried to find something on the internet, and the SmartBuyGlasses had the exact model that I wanted. Also, I sent so many e-mails for support in my purchase (how to make it properly to have a correct international purchase for myself), and they were very quick to answer me. The only issue was the long period to use my product (regarding to the shipment out o my country, and also in my country - 3 months waiting...). I think if you buy it in your country or somewhere nearby your country, it will took less time certainly.
