Review (3/5): Almost but not quite
I like that it keeps cloth mask off my mouth. Unfortunately it does not grasp the cloth folds the way it is described. Perhaps the mask material is too thick.
I'm sure it works with disposable masks. I also find i sweat under the bracket, getting kind of drippy after a while of walking. Good idea but disappointing. Nice that they c pico me 5 in a pack for families (I'm single).
