My current FFM an original "Quattro" with a puppy chewed forehead support works, but is not comfortable. After seeing all my numbers from last night (see other post - First night with O2 meter), I've got to make some changes and the biggest one is to stop the high leak rate.
My nasal mask is OK, but I had a bad enough night that it was leaking and did not wake either myself or my wife. So, I need a good FFM for nights I know will be bad at the very least, and I wish to try the Wisp on the theory that the smaller the area, the lower the chances of leaks.
It's a lot of $$$, but what can I do, it's my health!
