I received a pair of glasses with scratches on them and sent them back to be replaced. After waiting another couple of weeks for the replacements, those glasses were damaged as well. One customer service rep said they would "double check" the third pair of glasses to make sure they would be good. Obviously they have problems with quality control if they let two pairs of defective glasses be sent to a customer. Another service rep told me she could't see anything wrong with the glasses even though the scratches and other problems were clearly visible in the pictures I sent. It was the worst customer service experience I have ever had and I ended up buying glasses from another company.
