amon10 Posted November 5, 2016 Share Posted November 5, 2016 I've got the Opta mask setup. Was using just the mouthpiece and I was kind of confused because I had several old masks bagged together, including one with no vents( that one has no strap with big hook up in center, I could not tell you where I got it. Don't remember.) and having not been using lately because I'm out of cycle. I just try to continue to educate myself, first because I'm not exactly the "brightest bulb in box" and second because I want to be able to help others.
