Review (3/5): doesn't work for me
I have sewn reusable masks that I wear. I do not wear disposable masks. I think this was designed with disposables in mind. My masks have thicker elastics band that the button just can't hold well. I think the lighter weight disposables would do better with this headband. It was a nice idea but it did not work. I haven't decided if I am going to snip off the buttons and try and use it as a regular headband or if I will pass this on to someone else.
