Right now I have the gel nasal mask and it's ok. It still leaks some and blows air into the corner of my eyes and that irritates me. Hafta mash it when I first put it on and it normally does purty good.
Ifn ya mouf won't stay shut, it ain't blowin hard enuff. If my mouf ever opens, it's like a whirlwind comin out and I can't breathe a lick.
