Not secure enough
I wanted to like these -- the design doesn't get caught in hair, the length is long enough, the price is right -- but I join the others that the loop that goes around the frame is not rubber, but a more slippery synthetic that doesnt stay put, no matter how much you tighten it down.  After having my sunglasses fall off my chest the third time, I changed to something more secure.<br /><br />That said, I have one pair of sunglasses with wide arms and those haven't fallen off -- but the rubber doesn't stay on the arm in the same place - it slides around
