THESE SEEM WELL MADE AND ARE COMFORTABLE.  THANK GOODNESS THEY'RE MADE HERE
I HAVE ORDERED FOUR OF THESE AND GIVEN THREE AWAY TO PEOPLE WHO NEEDED A MASK.  WHEN I TRIED TO WEAR THE ONE I HAVE LEFT, I HAD TROUBLE GETTING IT TO STAY UP OVER THE NOSE.  IT WANTS TO SLIDE DOWN, AND I HAVE TO ADJUST IT CONSTANTLY.
