Great product
Why did I wait so long to get these. My glasses have been sliding down for ever. This has totally solved the problem. It's also nice to have them handily hanging around. These are well made and I'm totally happy with them.<br /><br />UPDATE<br />After using these for several months I've got to drop my review a bit. The problem is that the little bead you move to adjust the tension, after a while it stop gripping the strap. So it constantly loosens and you have to tighten it. It would be a better product if they had a way to lock the bead on the strap so it would not loosen.
