Best glasses lanyards I have found and I have tried a *lot*!
The short story : All good! Excellent value! Very pleased!
The long story : I have a predisposition to losing glasses, so I prefer to anchor them to my body with a lanyard, on the grounds that the only way I will lose my glasses is when I lose myself. I have tried many sorts, and all have failed in relatively short order - usually when the link that attaches to the frame gets weak and parts ... sigh.
These voltX lanyards have extra-chunky links, and substantial chords. They are comfortable to wear, adjustable in length - very useful! - and ...well ... excellent! Recommended.
