Was using a nasal cushion but because my mouth falls open when I sleep, I had to wear a chin strap. They wear out. Had to constantly buy new ones. The original one was no longer available on Amazon so I had to purchase several before finding the right one. It became a hassle so I thought I would try a full face mask. SO HAPPY. I love it. It does the trick. I gave it a 4 because I did have a problem with the strap that goes around your head across your checks and then affixed to the mask with magnets. It irritated the heck out of my skin and I have never had sensitive skin! I washed it. Same problem. Thankfully I had kept these little velcroed covers from a previous purchase and used them and have had no issues.
