not my favorite, it leaks a lot when i change positions and it takes some time to fix up and find a leakless spot for the mask, overall the service is great and fast

fantastic performance with minimal leaks, noiseless operation and maximum comfort. the quick release elbow is a brilliant new feature that makes the user's life much easier. my sleep has greatly improved since i purchased this mask and i will continue using it. a big thank you to multidoctorshop for their kindness in ansering all of my questions and giving me all the information I needed.

AirFit f20 is a very well constructed and strong mask.
It is almost completely silent and it never slips off, rarely needs to be readjusted. The strap material on the sides is very soft. The mask is also very easy to clean. However, I always breathe through my mouth when I sleep so no nasal mask works for me. I wish I knew that earlier. If this weren't a nasal mask it would have been the one.
I do appreciate the amazing construction, materials and ease of use, hence the good review.

the mask came apart after a little bit of use. not the strongest.
