I have bought these sunglasses for my son. After 2 months of use - nothing rough - the nose support broke. I Tried to contact the company's representative in my country but they refered me to the shop where I had purchased the sunglasses but told me that I will probably have to replace the whole frame and that this is not covered under guarantee. I wrote to the company in Italy - Luxottica - and never got a reply that took care of my problem. Evetually, I went to a shop that repairs these type of things a got it fixed somehow for $30 - so to summarize - poor quality product and ever worse customer service. I would have given it a rating of "ZERO" if it would have been possible.
