Not what it seems
While it keeps the mask away from your nose and mouth, the bracket isn't a soft silicone.  It's more of a hard plastic. You breath warm air and it gets trapped under the bracket and starts slipping around. It doesn't help you breathe any better and it doesn't stop the fogging of your glasses as it claims to. Will be returning this product as it was a waste of money. Good idea, not executed very well.
