the hinge area is weak and the temple snaps very easily from the hinge. i churned through all of them too quickly. i would not buy this product or recommend it.
all of them broke after minimal use. the hinge breaks. i could understand one pair breaking if not used properly, but all of mine fell apart at the hinge after just a few uses.
