Don't delivery as they promise. Take them forever to ship, and when you inquire about their delay, they alway have some kind of excuse. First I was told they didn't have the glasses in stock and they had to order them, then after they received them, they blame me on the delay, because I didn't choose the tint, when I did. After confirming the tint that I chose, I had to repeatedly confirm the tint to different people. Then they wouldn't cancel the order, because it's processing.
I ended up ordering my glasses from my local optometrist, and ended up receiving those glasses before go-optic could ship.
