Do not buy on Krintertrade, this page annouces that it sells original Ray Ban sunglasses at a disccount price, but really what they sell are knockoffs. And not even good imitations, these are plastic glasses that would not cost more than $5 dlls.
I tried to get a refund and all that they said is that it is not worth the time and money to send the glasses back to them (in China), so instead they offered me a 10% refund.
I paid $150 dlls and they only wanted to refund $15. not even the price of one of their products. In the end, I´m stucked with garbage and $150 dlls less.
