Background facts:
* Been successfully using ResMed nasal pillows for over a year but had to tape my mouth completely shut to stop blow-by. (A bit scary!)
* Have pretty mild apnea. Only require a setting of 6 cm H2O.
* As far as I know my Hybrid is not leaking. At any rate I don't hear any leaking noise.
* Not likely to get any help from my doctor. I had to order my Hybrid on-line because he wouldn't sell me one.
Please forgive the repost but I fear my first one was buried in the hybrid mask sticky and was being ignored.
