At first, I felt it very comfortable, but later on I started feeling a burning sensation on my cheeks and it leaked quite profusely from the top just right on my eyes.. I adjusted it and it was fine but the least change in position would it cause it to start leaking again. After a while I was able to use it for 3 or 4 hours but then returned to my old nasal mask at the middle of the night.. I tried for some more days but the irritation on my cheeks did not go away, so I decided to return it.
