The snoring chin strap. The first night, it quieted my snoring about 25%. The second night I lost the thing sometime during the night. The third night I went back to normal decibels. It's a scam! I wouldn't use another one if you paid me to use it. Also, the company has no internet site to call, complain or anything. Just an address.
Since I can't give zero stars, I am forced to give one.
Bottom Line: No, I would not recommend this to a friend
