*CPAPs doggone auto correct!

Traveling seems to be a popular way for caps to die. Mine also died after a flight home. I bought my S9 4 1/2 yrs ago and have always put it under the seat in front of me on flights now, so no more banging around in the overhead storage units.

Has anyone tried the head strap contraption that keeps your jaw shut along with the mouthpiece that moves your lower jaw forward? I'm not looking to replace my machine, I just want to be prepared for long power outages and I would like to backpack again.

I've had a resmed S9 for the past 5 years and am due to upgrade. What are the best next generation machines on the market?
