It works
It’s a necessary comfort you must do for yourself if wearing a mask.  The piece fits against the mask and your face easily and comfortably.  Quick to clean and dry, not that you’ll need to rush because you get 10 or more.  I teach fitness classes and it keeps the mask away from your mouth and nose with labored breathing.  This is the reason I purchased was for speaking and projecting clearly while teaching.<br />  It works like it should!!!!
