Overpriced brutally

For me it has brought nothing. Whether oral or nasal snorers, the air is passed over in the end, the same bottlenecks caused by the relaxation of the tongue and not by opening the mouth. The description tried a to convey that the air that is inhaled through the mouth, a waaay longer route to the lungs would have, than those that are inhaled through the nose. As geriete the inhaled air through the nose directly into the lungs and all is well again. Unfortunately, this is not the case.
The mouthpiece also does not push the lower jaw forward, which many other mouthpieces do to compensate for the limp tongue. While it is no dream solution, but such mouthpieces work in most cases at least.

I consider the many 5/5 star rating for very questionable. Who are these many people, assess all just a product over its entire Amazon career?

For me, this was an expensive and bad buy if you are looking for a serious remedy for snoring, then you are sadly disappointed.
