It does the job, not 70% more air as stated but still there is a noticeable difference (I suppose it might also have to do with the construction of each person's nose). For the gym it's fine, but for sleep, the second day I used it I got an infection in my nose even though I had disinfected it (maybe not well enough?). In general, they are annoying but I believe for exercise as long as it lasts it's fine, for sleep... it's annoying and it needs much better disinfection if it's going to be in there for so many hours.

It is so close to absolute nothingness that I honestly wonder how there can be positive comments...........

Works very well, at least for me. At first, the little ears pinch a bit, but then you get used to it.

I got it as a nasal dilator due to an anatomical problem with my septum. I wear it at night to sleep and in the morning for sports. The best product I have bought so far. I breathe comfortably and it doesn't come off easily at the slightest movement. It's not immediately noticeable to others.

Company No1, product No1 in its field, top in design, materials, etc., opens the nostrils like the Titanic's chimneys BUT....

no matter how much you try, it is incredibly annoying. Here in the instructions it says to wear it every day for 2 weeks to "get used to it."

While I have a serious issue and I like it as a product, considering it the best on the market... brothers, it's unbearable. It has a hook to prevent it from coming out of the nostrils, which bothers you as if you are a fish that just bit bait. I have thrown it away during my sleep because it was causing unbelievable irritation.

UNFORTUNATELY, we were unlucky...

It doesn't work, at least for me..
Even after 10 days, it didn't provide any relief, neither during sports nor while sleeping.

I have been saved both with the regular and the sport ones. At night, due to large nasal conchae, I couldn't breathe. The well-known external tapes did nothing for me. These open up the nostrils and I can breathe normally. I recommend them to people who face a similar problem on the roads.

I bought it more as a trial, and I have found that it is good. It goes without saying that it does not do the job of a CPAP for sleep apnea, just as an aid.

For sleep, a little hard but okay, it gets the job done. For exercise, simply no. And for both uses, the well-known sleep Right adhesive strips are better.
