The sunglasses are awesome but the product delivered to me was defectives. the tint of glass wasn't uniform on right glass. It wasn't a scratch but a manufacturing defect.
Its a genuine product and perfect fit (Medium Size). Came with a hard case (not solid) and with the cleaning cloth, warranty card, price tag and the sunglass itself. Btw the warranty card didn't have any info regarding the seller and date of purchase. Only a partial seal was there which was not clear.
Its better to try out in a store before making an on-line purchase since it will let you know if the sunglass suits your face or not even if its a medium sized one.
