I bought two pair. Within a couple of weeks. The first one fell onto the ground and broke in the corner. So I did not say anything or complain because I had bought another pair and thought oh well it's too much of a hassle and I just don't like to complain. However just today I was bending over in the kitchen after coming in from outside and they fell off of my face  And broke in the exact same location. I have pictures. This is totally unacceptable. I don't know how to contact the seller but I would like a refund or another pair. Going to complain to Amazon this is not a good product
