Mirage Swift pillow versus Mirage Swift ll

[Country4ever]

I've been using the Mirage Swift pillow for about 10 years. I think when I tried to order some pillows the last time, they said I had to go to a Mirage Swift ll pillow.
I tried it and it feels like my expiration is harder. Has anyone experienced this? It's uncomfortable, but maybe I just need to get used to it? I'm so used to Lincare screwing up everything that I didn't want to use it until I made sure I wasn't told the wrong thing.
The expiration ventilation is different between the 2. I know that nothing stays the same anymore, which is a pain, when the old thing works so well.
Any ideas if these 2 pillows are, indeed interchangeable? And if so.....is it possible that the newer one might give a sensation of expiration being harder?
Thanks.

I don't know about the comparison but I also use and like the Mirage Swift ll and have been for about 7 or 8 years. I keep trying new masks but I end up going back to the Swift ll

Thanks Greg. It just feels like it won't let me expire easily, but who knows......maybe that would help. I'm too aware of slight changes, so I might have to just bite the bullet and see if I can adapt.
I called the local Lincare, hoping to speak to one of the newer people who actually do a good job, and she doesn't work there anymore.
How can a business like Lincare keep functioning with such bad service? Oh well.....that's a different post!
Thanks for your input.
