Review on Chums Tech Eyewear Retainer Green by Keith Aluguvelli

I bought two transparent colorless cords several months apart. One has become rigid and inflexible, the other is excellent, soft and pliable. Seems to be poor quality control. I like clear because it's a little less noticeable when my glasses are on and when they're hanging. UPDATE About buying my sixth pair of glasses. They're excellent for the first few months, then the plastic gradually becomes stiffer and tougher until they're so tough their annoyance outweighs their usefulness. Then I give up and buy another one. I never had a single break. Please stay in place until the plastic has cured. No matter how much they cost I don't see why they can't use better quality plastic that retains its flexibility.
