It does not do what it promises + it also contains alcohol which destroys the normal flora and microbiome of the mouth, resulting in the problem worsening in the long term. No dentist will tell you to use a solution with alcohol, I guarantee it. If you want an oral solution that works 100% for bad breath, get SmartMouth and Therabreath, or better yet, Therabreath Plus, and also a good one with chlorine dioxide, Closys. Look it up and you will remember me, it is the best worldwide.

It lasts several hours, but not 12. If I wear it continuously for 3 days and then 2 times a week, I don't notice unpleasant breath, I have a mild freshness sensation in my mouth.

I am mild in taste. Maybe it doesn't last 12 hours, but at least it doesn't leave you with a stale mouth at the beginning.

It does what it promises indeed. It is the only thing that helped me. Just the 12-hour claim is a bit excessive. But definitely within the first 6 hours, you can tell, even after meals.

Strong action and enough burning in the mouth....
I couldn't make my pleasant breath last 12 hours at night....
Maybe I will prefer it again....

Since I tried it, I don't use any other mouthwashes. It comes in a smaller quantity compared to similar products on the market, but the daily dose you need to use is equally reduced, with a lighter taste than usual (mint aftertaste) and without alcohol. Gentle and effective. It doesn't work miracles, but it helps a lot. The promised 12-hour duration is up for discussion...
