These were actually for my husband.  I was SO pleased when they arrived.  High quality... retro...AND a wonderful hard case.  I think these glasses are a real bargain for the quality of the lens and the hard case.  My husband goes through them fairly quickly (misplaces them, drops them, etc)... I'll report on how well they stand up!
UPDATE:  Sept 2014... Had to look these up to order another pair... they lasted fairly well.  As I mentioned my husband is very rough on glasses.  The screw fell out of the hinge.  We did "repair" with a spare screw out of a repair kit... they will last bit longer.  He likes the full size lens and not the half size or insert.  I would still recommend them.
