I have bought Vincent Chase Sunglasses on last month through Amazon.com.And its cost me 3000 Rs.This product fail to satisfy their users because of poor quality and material.I use these glass daily and take good care of them but after few month I have noticed many scratches have appeared on the outer side of the glass.And I have realize that these product are not reliable.Though it was good in look but not so much impressive.I am very disappointed with this product.As it is very expensive though its not worth to its price.
