Help breathe easier

I tried the 3 sizes not knowing that suited me. And in the end, it's not bad because it allows a smooth transition to a larger model getting used gradually. Personally, I finally opted for the XL model. Well, it's not flattering (it looks like a cow with dilated nostrils and the ring between the two nostrils !!!) but it deviates from the nose to facilitate the passage of air. It does not reduce my snoring due to another problem, but it helps me breathe a little easier because I am constantly stuffy nose (allergies). do not mind at all, it is very easy to wear and do not deform. I adopted.
