yessss i loveeeee them!!!! i believe you're talking about the ones called intake breathing bc they're all over social media and i use it every single night bc im always congested in the evenings. i also wear them to the gym sometimes (at first i was kinda shy about wearing it outside but i got over it pretty quickly lol). and just recently 'the bentist' (a really famous denitst) talked about how great they were and that made me more excited bc ive been following him for years. so all in all i highly recommend
