Does Zyppah stop snoring? Yes, it absolutely does but if you need help, or have questions from the company, do not order this product. Their customer service is non existent. If you call, they send you an email to say they will get back with you, and they do not get back with you. If you email, they do not respond, regardless how many emails you send. Do not order this product if you need to talk to the company, or if you have any questions that need to be dealt with.
Bottom Line: No, I would not recommend this to a friend
