ZQuietAdvance, Custom Anti-Snoring Mouthpiece, Adjustable Mouthguard with 4 Jaw Advancement Sizes, Slim & Low-Profile, Clear

Great results on first night! I have been using an app to monitor/improve my snoring, and this device provided outstanding result in the first time use. See for yourself in the screenshots!

This worked great for about a month and a half then fell apart. It’s pretty expensive for not having longevity.

Could not mold to my teeth due to bone growth on the outside of my lower jaw. The hard plastic holding the molding would hit the bone and not allow my jaw to close enough to even make an indention. Product is non-returnable, so consider wisely. Due to them not returning my money, I will not be purchasing any of their other products.

This seems to help but it is uncomfortable. They need to design it for better comfort. It’s hard to wear it for more than a couple of hours.

This is not Sally , it’s her husband reviewing this. I’ve been on a CPAP machine since 2000, suffering from sleep apnea and heavy snoring. I can’t get thru the night without that machine. Or so I thought. For about a year I’ve been aware of devices that move your lower jaw forward to open the airway down your throat, but I knew a doctor would charge tons of money to create a personal device to do that. And then there was the gamble of it not working after spending the money. Recently I started looking on Amazon for these devices to see if I might find a good one. I read review after review and finally settled on this ZQuiet Advance. There are four settings to choose from in how far forward to move your jaw and when you get it, you must heat it up and then insert it into your mouth to make a personalized impression. That part was a bit tricky, but I got it done. I chose the number 3 setting as I’m a heavy snorer.It works!! Yes, it’s a little difficult to get used to; a bit cumbersome in the mouth, but now after two weeks of use, I’m pretty used to it. And it is so wonderful to be able to get a good night’s sleep without that mask, hose, and rushing noise all night long. And my wife loves it, too.I will note that after I molded it and used it for a couple of nights I had to take an x-acto knife to some of the material that squished out, as it was pressing on some of my gums a bit. But now this thing is working great; I’m getting a good night’s sleep every night. And I’m looking forward to traveling this summer without dragging that blasted machine with me and worrying about distilled water everywhere I go!This probably isn’t for everyone; some people may not like the thing in their mouth. As for my jaw, it does take several minutes in the morning for my jaw to realign, but it’s fine. If you have TMJ, this probably isn’t for you.

When you first get this product you will need to mold it to your own teeth. This involves putting it in a post of hot water for 3.5 minute. Of course it includes video and well written instructions. Once it has been molded to your own bite though it's ready to go. I use the other Z Quiet products (size 1) and know it takes a little getting used to. My first night it was in for half the night till I switched it out. Overall I love this thing and it definitely works. I will be using it all night as I adjust to it. No more CPAP to worry about!!!!!!!!!!

It works but with a what cost? It shreds the inside of your mouth and in the morning weird pain On the jaw… have mine over 60days followed all guidelines but still not comfortable at all. Unfortunately can’t make a return anymore

Do you not buy. It is a waste of good money. If you have a small mouth, it will be too large and can not be returned.
