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

Only giving 1 star because negative or even 0 stars is not an option.First and foremost this product does not work.Not only does it not work, it is extremely uncomfortable to use.Who ever designed this piece of useless material has obviously not used it and realized how absolutely rigid and uncomfortable to keep in your mouth for any amount of time let alone over night it is.Despite how uncomfortable it is I attempted to sleep with it in my mouth 2 nights in a row, I think I had it in the entire first night, did nothing but make it hard to sleep and had a sore and dry mouth in the morning. The second night I made it maybe an hour before I threw it on the floor beside the bed because I could not stand to use it any longer.Save your time and money and skip this purchase consideration...or not and come to the same conclusion yourself, it's up to you.

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.

See the before and after on snore lab. They don't lie I've been using this app and trying everything. Even the quiet results on the app are wrong I played it and it's just my TV before I fell asleep. There was zero snoring. I have tried nose strips, nasal spray, putting a tennis ball down the back of my sports bra so I won't sleep on my back... It really does take getting used to. I couldn't figure out how to get my mouth shut, after a while I could while sleeping on my side. This thing is not comfortable at all but I am told if I keep using it it will get softer and I'll get used to it. This was the last ditch effort before a sleep study and a CPAP machine. *Update after using this for a couple weeks it is still doing exactly what it is supposed to and my snoring is at a zero. But now my two front teeth hurt. I have had tooth trauma before so I know what it feels like and my two front teeth feel like they are suffering from trauma trauma. I'm not sure if it's because the fit is so loose and they don't customize them? But I have to find a different product that fits better

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!

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.

First, the good:1) It does work. My wife slept through the night for the first time in a long time, and we both woke in the early AM feeling super rested. Pretty impressed for the low price point. Similar devices from the dentist cost $1000+.2) Easy to apply. It’s as simple as putting in a mouth guard. You place the longer half on your bottom teeth and you can feel it pulling your lower jaw forward like it’s supposed to.3) Fairly comfortable. You’ll definitely notice wearing it, but it wasn’t cutting into my gums or pushing/pulling teeth in a painful manner. I slept through the night with no issues.The bad:1) Soreness. The jaw and teeth feel a little sore, but it’s supposed to go away after a few uses. Will update later.2) Unclear sizes. They offer two different options depending on your bite and the severity of your snoring. Regular/overbite people or mild snorers should use Size 1, while underbite and severe snorers should use Size 2. I chose 2 due to my snoring being pretty severe.3) Drooling. You will drool…quite a bit. But, if I have to choose between this or using a CPAP, drooling is a minor issue.Overall this is a pretty good device that does what it’s supposed to do. It’s not a cure all, but I noticed a huge difference in the quality of sleep I get. For $40 this is worth trying.
