These tie chains look good and are worth the money. The problem is that the back that hooks on the button is too thin. It easily detaches from the button when I'm working - leaning, moving, twisting, grabbing, etc. I've lost more of them than I can count as a result. They probably make them thin so you lose them and buy more. I won't do it again because I've found another one that's thicker, holds the button better, and isn't easy to lose.
