We bought a number of glassware pieces from Warby Parker previously. However, my last prescription pairs was a disaster. We bought their new concentric model with the blue hue. Well, they sent us a pair which obviously looks like it was used already - with both the model name and their own WP print faded. We sent two pics and it took them several days to come back to us to say they would replace it. Well, after several days of waiting, they sent us a new pairs and guess what - it was the brown one (not blue as what we wanted). Again, after another set of email exchanges, they then sent us another set... after four weeks. We asked to have their founders to address the issue. Of course, no comment from them. We ended up having to go back to their local stores several times to have the pairs adjusted. Their local staff is great, however. Their quality control is EXTREMELY poor as evidenced by what experienced. Buyers beware... They were used to be good.
