Ok, let's see if they print this. About a year ago, in 2017, I bought two of these chin straps. One for myself and one for my husband. We both tried them, and if you are a mouth snorer, they may work for you. But if you are a nose snorer like we are, they did not work for us. I heard my husband snoring after putting the strap on, and he was still snoring with his mouth closed. I sent those straps back. I do not recommend those straps, and they are a little tight too. I bought ours through Carol Wright.
Bottom Line: No, I would not recommend this to a friend
