This device is terribly overpriced as it is a piece of elastic cloth. It gave me severe jaw aches (I have mild TMJ). It simply clamps your jaw shut. If you get a stuffy nose, which is the main reason people snore, then you cannot breathe. I requested a reimbursement by email and I never received a response from the company. I now use a CPAP and I can vouch that the My Snoring Solution does not come close to the effectiveness of a CPAP.
Bottom Line: No, I would not recommend this to a friend
