I originally trusted this site because they were prompt to answer any questions I had (MANY) and they were super friendly. These were my first pair of designer sunglasses and I wanted to be careful because I knew it was a lot of money to spend if they turned out to be fake. I received my order after only about 5 or 6 days and it was carefully packaged. I was a bit surprising to find that I would have to pay $30 in import taxes although they did inform me of this. (not in the most strait-forward way but nonetheless) I am pretty sure that my sunglasses are authentic, acording to the research I've done, but have yet to visit a registered dealer to confirm. Very happy with my purchase from this reliable site.
