I've been using the ResMed F30 Medium hybrid mask for almost a year now. So I thought it would be nice to share what I have learned.
Headgear...
I switched headgear about six months ago. The F30 headgear was causing a dull headache at the back of my head where all the straps converge. It just wouldn't go away. So I switched to the the Amara View headgear 1090697. It is available on Amazon and Ebay for around $20. The ResMed headgear would work OK as far as headaches goes if I loosened the straps. But then it would leak quite easily. Snug it up to prevent leakage and the dull, chronic headache would come back. The Amara View has a much larger pad where the straps converge (and where my headache was) and is infinitely more comfortable for me. Also, the Amara View has an adjustable top strap. My ResMed does not. I think some of the new ResMed F30 headgear may have an adjustable top strap. I have seen it in pictures only. Photos #1 and #2 below show the converging pad size difference.
Another bonus is the Amara View has larger velcro pads on all adjustment surfaces - maybe 75% or so larger. This makes the headgear last longer than the ResMed headgear. The magnetic clips will have to be swapped out with the ResMed style clips. Photo #3 shows the difference. I replaced the Amara View headgear after six months. I probably didn't need to, but I do notice a slight difference with the new one. The ResMed headgear stretched out a bit after six months. Each tentacle (for lack of a better term) stretched about 3/8" in length requiring periodic adjustments. The Amara View didn't noticeably stretch during its six-month term.
F30 Cushion...
I have found that the F30 cushion still performed well after nearly a year. It slightly discolored, but seals well and is still very soft, and pliable as new. I replaced the cushion anyway. Replacements are cheap enough. The old one is now marked for emergency use if needed.
Comfort...
After 11 months, I am still very happy with the fit and operation of the Medium F30 cushion. The Amara View headgear was a huge improvement. I nearly always sleep on my side and seal and slippage is not a problem.
Is the F30 for you???
I wish ResMed would make a large F30 cushion because the width of the mouth opening probably won't accommodate someone with a mouth wider than the average mouth. Fuller than average lips might also be a problem, but that is only speculation on my experience being of somewhat average facial features. I would also guess the small version would only be usable for people with a fairly narrow nose and fairly small mouth. That being said, I know the F30 would be a complete disaster for a number of people outside a somewhat tight range around average. With only two cushions to choose from and an infinite variation of faces, ResMed could serve its customers well by developing a few more variations of the cushion.
If you think this report helps guide you to try the F30, it could be a great move. And I'd love to hear more people chime in on what works, or not - success stories or difficulties. ResMed would clearly benefit in sales by offering more cushion choices on an otherwise outstanding product.

Sorry about the weird colors. The color temperature of my lighting was less than ideal and Photoshop couldn't quite correct it all.
