I ordered these glasses and when they showed up I absolutely loved them, they were very high quality and well built. The only issue I had was the glasses were a bit to small for my fat head and I was just going to suck it up and deal with it but then I got a e-mail for a company rep asking how I liked the glasses. Upon mentioning the issues despite being told there was a no refund and no exchange policy when checking out they offered to exchange the glasses for me so I could get a pair that fit better. Unfortunately I was storing the glasses in my can and someone broke into it before I could send them back for an exchange so I'll just have to buy a new pair.
Overall great glasses from a great company with great support. Highly recommend buying these glasses and working with this company.
