Horrible product
I bought two of these and it's a good thing I did. I tried to use it for the first time about 3 days ago to start running again.The ends that slip over the glasses are made of what looks like a slick soft plastic. I put them over the earpieces on the glasses and tightened slightly. As I put them over my head one end slid off the end of the earpiece. I tugged on it a bit harder to try and tighten it more and the metal piece that holds it to the elastic broke in half. Put the second one on my glasses and had to be very careful to not break it. I just recently found the ones that I wore in the Marine Corps when I ran and they're still in pretty good shape. I got out in 1993 and probably bought them about 5 or 6 years prior to that. I probably went through about 3 of them during the whole time I spent in the Marines. Do not buy these, it's a waste of money. They should not be allowed to be sold on Amazon.
