What does anyone know about No Mask

Has anyone ever tried this mask? It looks really comfortable, but does it work?

I don't think many people here have experience with this mask though it has been discussed in the past.

If you go to the forum search at the top of the page and search for nomask you will find some posts in the past that have discussed it.

Some recently may have used it or are using it and might stop by and offer comments but in the meantime check out those old posts and see if anyone had much to say about it.
