ZQuietAnti-Snoring Mouthpiece, Comfort Size#2, Single Refill, Clear, Made in USA, BPA-Free, Medical-Grade Material

This product is a big rip off! It doesn't work, and IT'S NOT RETURNABLE!The tray where your teeth go is 3/8 inch wide. No one has teeth 3/8 inch thick! So the device doesn't stay in place, and that's supposed to be the point of the whole thing. It has to stay in place so the lower jaw doesn't relax and cause snoring. DO NOT BUY THIS PRODUCT! Your money will be wasted!

I read all the ratings. For me, this is the single most positive influential product I have ever bought in my 54 years. Used the mouth piece the first night with the sound app. I used the mouthpiece until I woke up around 1:00. Took the mouthpiece out and reset the app. My snoring level with the mouthpiece in was a 4, without a 76. Next night, with and without the mouthpiece....scored a 6 and 78. The third night was the ultimate test. My wife slept in our bed. My snoring has been so bad, she has to sleep in our Guest room on work days. She woke up in the middle of the night because it was so quiet. She thought I had got up and slept of the sofa, my snoring was so low.The mouthpiece does feel strange in your mouth. And in the morning, there is some saliva built up in the trays. Not like slobber, but there some saliva in around your teeth in the morning.Given those two issues. For me, this mouthpiece has all but eliminated my snoring. Not sure if you will have the same experience but I am amazed how well it worked.

Not totally effective, and tends to ache after a while, at start of use caused salivation but dry mouth by end of night

Doesn’t allow adjustments. Doesn’t really hold your mouth in place to allow the under bite trick to work. Imagine a snoring device designed by a 4 year old and you’d get this.

Like many others I find the product to be lacking in so many areas it does not sit firmly in the mouth and is very uncomfortable.......it does not fit and barely does what it is intended to do which is a disappointment.....needs extensive improvement.

This has been the only device that has worked for me after trying all the other items like nose strips, jaw straps, pillows. I went to an ENT Dr who recommended. I have to replace every 6-9 months as they do wear out over time. My wife lets me know when it’s time to reorder. The only time I can’t wear to sleep is when sick or super congested and unable to breathe through my nose. Wife says not as effective sleeping on my back but I am mostly a side sleeper so no issue. There is some minor jaw discomfort at first but after 3 plus years of using there is no issue at all.Based on the other negative reviews it may not work for everyone but it was the right fix for me. Highly recommend to try for the price point.

The product works pretty good

I found the material too flimsy, the tooth channel to shallow, the ability to hold teeth without sliding out of the channel was non-existent, the distance it drew the lower jaw forward was simply too much with the flimsy material involved. When I relaxed my jaw the hinge would roll and not even hold my jaw in place and my teeth would slide right out of the channels because they were too shallow because the channel material was too thin and flimsy and because there was some material in the channel that actually kicked my teeth out especially my upper teeth. It seems like a good idea but without a more substantial product it's never going to work. There's no way to keep your jaw from the relaxing both down and open and this device does not take either motion into consideration. You would have to lock your jaw closed and hold it forward in order for this to work and I don't know anyone who can do that unconsciously.
