Thanks for sharing, Dale. I think I'd go nuts having to switch back and forth so much to try to determine which was better.

It seems my experiences haven't been that bad compared to some others'. I've become accustomed to readjusting my mask during the night, but of course I'd rather not have to.

Bump.
Interested in seeing if anyone who logs on today has had any experience with Ultra vs Quattro.

Thanks for the link, SleepGuy.

Man, now I don't know what to think.
