Very nice for breathing

Horrible and useless product and also unjustified expensive. The taste is very bitter, actually too much bitter, also burning your mouth and the effect is nothing else than make you spit it in the sink. Don't waste your money for something so expensive and so unpleasant.

No benefits of using this product it’s just some harsh spice on your palate, same feel when yo take some menthol.

I was very excited when I saw its ads so I bought one. Big disappointment and return request followed that quickly.
