We were really hoping this was going to help my husband's apnea that is life threatening, but it doesn't work for him. And now that they have my credit card info and locked me in on payments. I can't get ahold of anyone or if there is any way to return it during our "60-day free trial." Every way to contact them says they are sold out or too busy to answer my questions. Terrible customer service.
Bottom Line: No, I would not recommend this to a friend
