I have been snoring for a number of years and my wife really had reached a point where she had enough. A friend reccomended a product they had heard of which was new and they saw on a Google search.
All I can say is - it stopped me snoring the 1st night.
It seems odd at 1st as it restricts the flow of air into your nostrils, meaning you have to breath through your mouth. It is quite comfortable and I have reordered since.
All I can say is give it a try as it worked for me.
