After more than a month using my Silent Nite retainers I have had the best sleep of my life ....just ask my wife. My airway feels as though it has doubled in size because I feel like double the amount of oxygen is passing through it makes me sleep like a baby. Awesome product. I would recommend it to anyone who is having trouble sleeping and/or snores. This is a miracle product. Thanks again Dr. Dykman and the Bullmoose team!!!
