I’ve been using the nasal cushion. Best in 20 years but wondered if full face could be better. Ordered medium…way too big. Small is ok but I wish it were a bit smaller. Still getting used to the huge presence on my face, air feels good, not yet sleeping well - night used nasal and got a good night’s sleep so alternating may be the way to ease into it. Memory foam is a game changer for comfort. Why aren’t there more options?
