I have one of those things!
I got it a good few years ago when I went to a respiratory therapist (yes, they have a therapist for everything it seems!) She gave me one with saline solution and I have to agree, it is a deliciously awesome feeling! You feel so un-clogged afterwards.
Problem with me was it always seemed to come out my mouth too! So the lady told me I had to make sure to always breath out while doing it. Still, feels good man.
Sometimes if you use heaps of pressure it can even come out your eye sockets!
ps. hi happy
