My reading glass frames literally just fell apart before my their first year of use. This forced me to examine them more closely. Holy Cow what cheap crap. The wing hinge tab just corroded away. It was microscopic in size. I was amazed that a frame would be made to fall apart. When I went back to have the wing replaced they said they don’t have the parts. Their response has been to become invisible on the web. They do not appear on google maps at all. Thank goodness for Unilocal
