I've been using 3m micropore tape. That too worked great but after a couple of years it became brutal on the lips. I got to using vaseline to protect my lips from the tape. It got too complicated. Tried this product and its far more gentle and still sticks quite well, even to some beard stubble. So, it sticks well and is gentle. Oh ... and it keeps air from escaping from my lips while using the CPAP machine. Bingo.I use a CPAP and have a couple different mask styles I use depending on my allergies (do I have a stuffy nose or not.) I found that I would sleep with my mouth open when using some of the larger masks. A friend who also uses a CPAP told me about mouth tape so I thought I'd try it.It works better than I expected. It's sticky enough to stay attached all night but doesn't hurt to remove in the morning or leave any marks. You can still talk and breathe through your mouth if necessary but it keeps your mouth closed while you sleep. I've actually been using the mouth tape in place of my CPAP a couple nights a week and no snoring or waking myself up gasping for air.Great product.I have to wear them sideways, as they are much too long to wear as shown on the picture. Maybe my mouth isn't big enough?I use nasal cushions with my cpap machine. The strips keep me from breathing through my mouth while sleeping. Works well.The texture is rough and the piece is too large for my face and uncomfortable yet the tape doesn’t stick well and falls off in the middle of the nightI bought this tape to keep my mouth closed at night while wearing my cpap machine. But after I ordered it, I instantly regretting doing it. How will tape possibly stay on your mouth when it is moist and you move in the night? Too, I have thin, sensitive skin and I expected it to tear it. None of the above happened. The tape stays all night long. And when I start to take it off, it stings for a minute. But it doesn't tear my skin and to my surprise, it didn't even make my skin red. I'm pleased and I'm really sold! I'll be buying it from now on.I love these. I use one every night. Helps me sleeps better. These stick on very well.First time I've seen a package the same as the picture for X mouth tapes. However, the price is higher, and I kind of liked the little plastic envelopes they originally came in.
