Query: Didn't worked for me

I snore because of the overweight. Used the product for almost a month. In my case it just didn't worked well. I stoped snoring from time to time but I can't be sure it was because of it. Besides, I lost my Nozovent like 3 times a week while sleeping and after that its really hard to find.I don't recommend it.
