Posted by Darby on July 15, 2008 at 13:30:39:well i did it. I bought the nasal aire II with all the prongs in the package this time after hearing it hyped on another forum. I used this thing 2 years ago and it was OK. thing is, I had the wrong size and never knew it. I was wearing a size too small. going one size up has made the difference between giving it a 10 and it being a 5 or 6 before. I like it better than my swift II, that's for sure. I would have never known. Why the heck didn't they sell all the prongs 2 years ago.I guess they were too cheap. I've had 9 masks in the 2 years since I first tried it. I could have saved myself a lot of grief. who'd a thunk after all this time.
