I purchased the Smart Nora system about a year and a half ago. I did so because it was one of the few products for snoring that did not require things that go near my mouth and nose. I have claustrophobia and could not tolerate these products. The Smart Nora system works so well my wife makes me take it on vacation, good thing it is portable. My one complaint is that I have had three motors since my purchase but the Smart Nora team has sent me a replacement each time free of charge.
Bottom Line: Yes, I would recommend this to a friend
