For mild - moderate obstructive sleep apnea, they can be very effective. As you go from moderate to severe, they may not be effective enough.
Maybe that was my problem: the home sleep study showed me to be WAY into the "severe" zone. No wonder the cheap $20 Amazon mouth device that I'd tried beforehand, didn't do [fecal material]. Even once I got the machine, they had to keep upping its effort to get it to work effectively.
Perhaps my roommates on the 24HCF hog hunts weren't exaggerating about my snoring, after all...
