The cable retainer is great. Strong, yet light and easy to use. My only wish would be that it would close up tighter against your head. I wear it with the sunglasses I purchased from you, and we go to an amusement park and in order to ride the coasters, you either have to have the sunglasses tight to your head or remove them. I pulled them up as far as they would go, and while they wobbled a bit in the wind, they didn't come off, so for that I am happy.
