I have OSA, and this thing has worked for me. I couldn't get used to the CPAP. This may not work for every one, but it worked for me, and was only 60 bucks. For me it was a no brainer to try it. My wife says I am no longer snoring, no longer am I stopping breathing. I feel much better in the morning, and no longer tired during the day. If you have ever had braces you know what I mean by a little discomfort to get used to. My teeth, and jaw ligaments are no longer sore in the morning. I should add that I had a rhino plasty last year to have a deviated septum fixed. I am not sure if this would have worked pre surgery or not.
Seriously like Patrick said if you think you have OSA get a sleep study, I did. If the prescribed stuff doesn't work then you have another option to fall back on.
