Terrible quality for Burberry
I am really careful with my glasses, I have some Gucci frames for 20 years now. These did not even last me 6 months. The Burberry color turned out to be a sticker which came off in a couple of months. The hinges don't work well and they keep slipping off my nose every few minutes. I had very expensive lenses fitted in to these frames and they should have lasted at least 2 years. Now I am stuck with uncomfortable frames that just drive me crazy.
