Purchased 1 of each competitor and this was the best. Hook is well positioned to hold glasses without the glasses becoming entangled in the hook. Two things I didn’t like are that the elastic is very firm, not much stretch, so it squeezes the head noticeably. Yes it stays put better, but do have to remove it for periods to avoid headache. Second is that the strap is too sort. I have 7-1/2″ head and on maximum adjustment still could barely get it on. First tried to unhook the strap, but couldn’t get the attachment apart so had to cut that strap and sew in a splice. All that aside was still better than the others offered.
