I liked my first one so much I ordered another one.
I bought a fit pack which consists of a size medium mask setup, with four different nasal cushions in different sizes. Cost $125 AUD from ebay Australia. According to the listing's given measurements to select a size, I used the measurement I took to choose the medium.
The second one I ordered was the small size at $120 AUD from the same ebay store, for the reason stated below under Cons..
Pros:
Lovely easy swivel away from the face for comfy rolling manoeuvres.
The little size guide that comes with the mask is handy for selecting the cushion. Not that I've tried any of the other sizes than the small.
Leaves way fewer marks on my face.
The cushion is very comfortable.
Lots of leeway for adjustability.
No noisier than my pillow masks.
The little cheek covers are a lot more effective than the thin ones that come with the Swift FX. They're nice and fluffy and wash up nicely.
Stays put for tummy and side sleeping comfort.
If adjustment is required in the night, it's easier than the pillows to get back on track when half-asleep.
I didn't find any part of the setup intrusive or uncomfortable.
No harder to clean than my pillow masks with their hoses.
The price was great for buying in Australia. I figured if it was a dodgy knock-off, I'd just send it back, but the goods seem very much legit.
Cons:
This isn't really a con for me, but others might not like the faint sound of air in tubes. It's not loud, but it is distinctive. I don't mind it at all. Some might even find it mildly reassuring.
Again, not really a con. Rather a thing I learned: I found that after a couple of nights, the whole mask relaxed in size a little bit. Not much, but enough to have to slightly adjust the straps. I don't know whether it will continue to 'stretch' over time, but I still have some room for adjustment on the medium mask. My second mask, in the small size also fits well (being a between-sizes in reality versus on the measurements in an online listing for once has proven advantageous for once in my life), although I haven't slept in that one yet (it arrived this morning), but according to the mask fit function on the machine; and the comfort, it bodes well.
The other 'con', but only a mild one, is that in the absence of that extra bit of hose, it's very easy to forget you're attached and find yourself yoiked back if you try to sit up or reach the cat for a pat in the night. If I could get used to having a hose on my face, I'm pretty certain I can get used to that. I haven't found the presence of mind in my usual morning torpor to engage the quick-release attachment as yet, so I'll not specifically comment on that at the moment.
All the above aside, it's also been a source of amusement.
When I first tried on the medium mask, I got a bit of a fright when it simply fell down around my neck. The straps in their loosest setting. The relief when I realised that I hadn't grossly overestimated the measurements of my bonce.
And today, fitting the new mask before attaching the hose, the easy swivel mentioned in the Pros above was swinging wildly with each movement of my head as I was fiddling with the machine display to test with air. The thought of being a teletubby made me smile.
LOL!
And finally, being used to pillows, I was going to order some pillows to go with the masks. But I'm so happy with the cushion that I don't think I'll bother.
[Minus one point for performance while sleeping on my side]
