Bought a total of four of these sunglasses as I was going on a trip. Two of them fell apart within a few days of use each. They didn't break, they are just so badly constructed, the screw that holds the hinges just fell apart resulting in glasses literally falling apart on the street while I was wearing them.<br /><br />If this happened to one unit I'd understand, since it happened to do its very clear that they Quality Control team definitely needs a tune up.
