Awesome mask. Easy to setup even though no instructions are included. I do let the masks air out for a couple days once received. There is a piece that I have no idea how it goes on the mask.
I Love it! I thought I was a missing piece to the face shell but I think it's just different from the other 3 I have. There are still a few that I want. I'm just waiting for a sale. Keep up the good work.
