This thing has saved my wife's sleep, and us being able to sleep in the same bed. We were about ready to try separate bedrooms because she was a wreck with bad sleep and exhaustion from my snoring. Saw this was FDA approved, had a 90% success rate, and a free return label, so figured I'd give it a try. I have literally, per my wife, not snored a single breath since. It's been almost a month. Kind of can't believe it. The only thing that remains to be seen is a little bit of pain in my bottom front teeth where it pulls the jaw forward, hoping it doesn't mess up my teeth or bite, but it's been very easy to get used to and sleep with and even if it does, I'll probably just deal with it for the amazing results.
