That’ll work for someone whose only or primary breathing obstruction is nasal valve collapse.

I had enough nasal valve collapse that I tried these vents but found them uncomfortable. I got the desired impact on my nasal airway from nasal strips that keep the nasal valve open, but that didn’t solved my nighttime sleep/breathing issues because I also had a very narrow airway into the back of my nose and throat due to my recessed upper and lower jaws, which I had surgery to correct about bit over a year ago
