Peeper KeepersRetainer, Sunglasses Holder, Eyeglass Chain for Men and Women, Navy

Perfectly held my reading glasses. The rubber devices on the ends do not slip at all, apply easily to your glasses and retain their grip over time. Cheap but tons more effective than more expensive cords. Works much, much better than those cords with the little plastic loops on the end.

Simple chord with soft plastic squares that slip around the side eyeglass frame parts to hold it firmly in place. Not sure how these plastic squares would hold if I were to frequently take them off and on.

Excellent - the rubber attachments that slid onto the temples beats others by a mile

This is a piece of junk. It fell apart where the cord joins the rubber fastener within two weeks of using it.
