I’m not new to mouth taping, but have been using a 3m tape to do so. It tended to irritate my skin and leave a residue, so I decided to try these. They stick well at first and don’t cause irritation, so I do love the concept. However, because they’re mouth-shaped, they don’t stay on the entire night. The corners have drifted into my mouth every night I’ve trying using them (I assume when I attempt to open my mouth while sleeping), which then causes the tape to become wet in the corners and loosen, eventually lifting all the way. They have not stayed on an entire night since receiving them, which is disappointing. I think the focus on aesthetic compromises the quality. I’ve attempted to reach out via email and website to see if I can take advantage of the happiness guarantee, but have yet to hear back. I would have loved to know if the company had any plans to make another shape, but considering they haven’t even responded to me, I’m not sure this is a company I’d support even if they did make another shape.
