Title: Amazing
Review: This product works!! And it's NOT a medication that cripples your body's natural mechanism. Thank you... whoever invented this!!One thing: the instructional CD/DVD that came with mine was broken. I was annoyed at first and then I found ALL the videos on you tube. Simply search for `powerlung' on you tube.Caution for the new users: MUST go through the video since the written instructions can be confusing.
