I want to start by saying that this is a genuine review. I am based in New Zealand and bought from the NZ site.
I was a bit worried after reading the reviews. But nonetheless I purchased a pair of Ray-Bans at the cheapest price online - well except the ones that are clearly fakes. I got free express shipping. They didn't have my ones in stock but they sourced some within 5 days-less than the time-frame they suggested. One day after postage, I got an alert saying that shipping is delayed. Oh No I thought. Here it comes. But no, the product turned up the next day, just 8 days since purchase for a product not in stock at the warehouse. And after inspecting them, they are definitely genuine- I have had this model before.
I am one of the few on here that CAN recommend SmartBuyGlasses.
