They work as suspected. Simple product. Only dislike is that you are asking me for more than stars in this review. The retainer may not be strong enough to hold heavier glasses or sunglasses.

I bought these to hold my glasses on to my face while riding roller coasters at Cedar Point. They have some very intense coasters. The Chums kept my glasses on my face throughout all the rides. They didn't even come close to coming off. Was very satisfied.

My sunglasses stay on now and I no longer have problems with them falling off my face.Pros:Simple deviceGood priceCons:For my Cacoon fit overs, it took a lot of stretching to get them to fit the handles.

This a great retainer to have for your glasses.I have recently purchased this item because my classes were a bit too heavy causing red marks to appear on the inside of my ears. This, of course, resulted in a lot of pain and I was generally uncomfortable.I needed to wear my glasses for a long period of time, so I looked online for something that would cover the glass's temples to prevent direct contact with my ears. Then this popped up.So far, I had almost no issues with these retainers, and in…
