The magnets on these are seriously strong. I put my glasses in and they do not budge all day, no matter what I am doing. I have tried other holders before and they felt cheap and weak. This one actually holds. My glasses feel safe on my shirt and I never worry about them slipping off.

I used to lose my reading glasses ten times a day. I would set them down and forget where. Worse, I would hook them on my collar and they would hit the floor every time I bent over. One pair even broke that way. Now they stay right on my shirt where I can find them. That problem is just gone.

I will be honest, I did not think something this small would actually hold my glasses. It looked too simple to work. I was wrong. It grabs on and stays put even when I am moving around the house or getting in and out of the car. So glad I gave it a try. It does exactly what it says.
