I tried the Liberty long ago. I always have clogged nasal passages. It was uncomfortable b/c the seal above my upper lip would always come down on my upper lip and irrate me. not comforable at all.
Last week I went and got the fitlife

I really really like it...except I have the opposite problem that I did with the Liberty. The lower seal comes up onto my bottom lip when I open my mouth
So I'm wondering what I should try next. I have found the following interesting. I would appreciate any suggestions.
Respironics Comfort Gel Full

Respironics Fulllife

Or an out of the blue mask since I liked the fitlife, Respironics Total Face

It looks like it would seal under the chin instead of under the lip
