Overall I like the product but I think they may be just a little bit heavy for my glasses. I also wish I had purchased the smooth ones because the ones I purchased get a little tangled in my hair. They have definitely helped to keep my glasses from slipping and pinching so overall I am happy with them.
I've already re-ordered a set of these and have had co-workers ask about them. The only issue I had was the rubber band had broken but when I sent an email asking what to do, they immediately sent me a few spares. (I would suggest including an extra set of rubber bands with each order.) Overall, very happy with product.
