This cpap stuff has come a long way since my first cpap machine -- a hair dryer with the heater disabled and a hose glued on.
Naw, just kidding, but when compared to my new S9 that's not far off.
I've worn out two machines in the last twenty years.
In all that time, I went just one night (years ago) without my machine (I forgot it on an overnight trip).
That was the worst single night of my life by going back to the apena/snoring. Never again.
I suppose I'll get into all the data stuff and what not like most of the posts seem to center around, but for now, I'm amazed and satisified with the quietness of the S9 and the Breeze headgear comfort over my old Puritan Bennett ADAM Circut headgear.
In the end, it's about waking up in the morning.
Thanks again for a terrific source of information.
