I have bought at least 5 pairs of reading glasses because they are among the most beautiful (for their price). In all of them, the sides have come off without me having the chance to use them extensively. The screws that hold them together constantly come loose.

Whatever Zippo glasses I have bought are unacceptable. Both for sun and vision. The first two for vision were defective and the arm broke on the third one without any pressure after 2-3 weeks and of course there is no mention of replacement from the supplier... They are NOT worth it
