Cloth Masks do NOT stay on well
I like these extenders but for one major flaw - the hook area is so small a cloth mask (if the ear hook is not as thin as the one's found on medical masks) will not stay on defeating the entire purpose of what they are supposed to do. I thought the silicone would help, and it does for staying on my head, but not for the mask. If the hook area was a bit deeper, I think these would be perfect. Probably 5 stars if you are using with medical masks, not so much for any other kind.
