Pretty good for breathing, takes getting used to
Works ok, takes some getting used to. I think I'm in between sizes so it's hard. I tend to sneeze a lot and get runny noses due to the foreign object. I think it works pretty well, I mean when I'm awake I feel that I can breathe a lot more easily through my nose, I don't have an app or sleep quality device to track so I have no idea if it really works, I haven't really been able to use it all night, maybe a few times.
