This may be okay for a one or two quick uses because I'm sure the components that make up this mask are not going to last long. The one piece elastic is not of good quality and stretches after fitting is adjusted. After fitting, the mask did not leak with testing. There was a slight smell from the mask, which surprised me. These components usually stink of chemicals. Here's the kicker, within four minutes my face started burning where the mask made contact with my face. I had to wash my face, not rinse it.
