Originally got these for girlfriend who sometimes snores and wakes me up in the middle of the night. I decided to try one out myself and it enabled me to breathe so much better. I couldn't believe how much more airflow i could get while inhaling with this device in my nose. It was if something was blowing air into my nose. I actually slept a whole lot better going to sleep with one of these. It was first time in a long time I slept a solid 9 hours without waking up one time. I will forsure be using these for myself now.
Output:
positive
