Despite the low cost of this glasses, they look nice overall. But I must point some flaws that made me feel a bit down: 1- The writings on the internal frame are misspelled. "American OPITAL". that is unacceptable, even on a cloned product. 2 - The UV protection left me concerned about the efficacy. In the attached pictures, the left sunglasses is an original Ray-ban which, as you can see, blocks all of the UV, letting a little light to go through. With your sunglasses, you can see in the picture it only partially blocks UV light. I did the test with a bank note and the Ray-ban does not let light shine the security marks in the bank note, your sunglasses lets dangerous UV still to light up the security marks in the bill. This is a safety reason we buy glasses with UV and this product does not conform to it! 3 - The lenses shows deformations in the corners, external and internal sides.ç See pictures attached. I hope you can use my feedback above to improve your product. Thanks.
