[check updates at the end for a comment on a 'Snoring Lab' app]

My snoring was keeping my wife awake, or causing her to sleep in the guest bedroom. Vacations and hotels were a particular problem. And it got worse with some weight gain during the Covid year. A friend recommended this type of solution (he eventually had a custom set made by a dentist). My wife and I agreed to give this a try. I'll attempt to return to this review every day or so to update the review as long as there is new information. I read the companies information, and many reviews, positive and negative. I had an idea of the range of experiences to expect. I started with the #1 mouthpiece, as recommended.

As for "Value for the Money" - the two supplied mouthpieces feel well constructed. The plastic is thick and sturdy, yet pliable, as it needs to be. There are no burrs or sharp edges. I think they recommend replacing them every... six months? After my initial two nights, I expect it to last that long, easily. Still, they are just two pieces of molded plastic, and manufacturing them at scale has to be pretty cheap. Many things go into setting a price of an item, and 'perceived value' means setting a higher price may make people think the item is 'better'. If they sold this for $10, would I dismiss it as just a piece of crap? Hmm, they do offer a subscription that I didn't check out. Maybe the subsequent purchases will be much cheaper? [UPDATE: 10 to 15%, so not much cheaper)

NIGHT ONE: NO SNORING. But also not much sleep. As fully expected, the mouthpiece was uncomfortable, but not unbearably so. I felt pressure on both upper and lower front teeth, and it was odd (and uncomfortable) to have my lower jaw pushed forward, even that small amount. It was enough to interrupt sleep often, though I probably slept more than I thought I did.

The literature recommends trying the device for short periods before using it all night, to get used to the feeling. I didn't do that, but I did stay awake reading and listening to podcasts for a while before 'shutting down'. I was able to 'tough it out' (not that tough) and keep wearing it all night.

The literature (and my friend) also warned me to expect that my jaw might feel sore, and would be a little 'out of place', when I removed the device in the morning. That was true. My jaw was still pushed forward a bit, and the 'bite' was off. That lasted for a little under an hour, when I noticed that all was back to normal. It felt a little sore for a short while.

NIGHT TWO: NO SNORING. I didn't always snore, or at least it didn't always keep my wife awake. But again this morning she reported not hearing any at all. Now I will say that she has a vested interest in the success of this experiment which might slightly skew her report in a positive direction, just to keep me going across any bumps in this road. OTOH, I sometimes do hear my own snoring. Sometimes it wakes me up. None of that the past two nights.

On night two, I slept better. The mouthpiece still felt odd, still uncomfortable, still put pressure on my teeth, but noticeably less than Night One. My jaw remained out of place for a while (half hour?) after I removed it. My teeth feel normal now, in mid-afternoon, with no lingering effects.

NIGHT THREE: a little snoring early, she reports, but I stopped when she prodded me to roll over (which I don't remember). I slept better, probably about average, which means I woke up ever few hours to pee. The mouthpiece was 'less uncomfortable'. And still about a half hour to feel normal after removing it.

I'll add that it's easy to clean. I use a surplus toothbrush and dish soap. There are no hard-to-reach crevices.

NIGHT FOUR: No snoring. This is the first night I can report that my teeth didn't feel sore at all from pressure. I'm not saying it's comfortable. That'll be headline news if we get there. But it didn't hurt, even a little. It's been out about a half hour, and my bite is returning to normal, though if I clench my teeth some, I can feel a bit of tenderness.

One thing I haven't mentioned, but the literature notes: drooling. I sleep with my mouth closed (AFAIK). The mouthpiece doesn't allow my lips to close perfectly. They are closed, but it doesn't take much for them to open a bit and drool a little saliva. This is a minor thing, but something to note.

I didn't sleep well last night. I went to sleep about midnight, and was awake from 4 until about 7, then slept until 9:30 (I'm retired, and usually sleep in with no alarm). I'm not blaming the mouthpiece. Note that it didn't keep me up the night before, and this happens now and then. But one of the advantages the manufacture suggests is better sleep. I don't expect that at this point while I'm still getting used to it. It would be nice if that happens.

NIGHTS FIVE, SIX, SEVEN (Maybe Eight, I've lost count). We've been in a hotel on vacation the past four nights, and my wife reports little to no snoring. At home, she was able to escape to the guest room when I was snoring. Not possible in a hotel, so the goal was to make this vacation work, and it's been successful.

As I mentioned, I'm getting used to it. My sleep has been iffy. Last night was pretty good. I'm looking forward to 'better sleep', but while it doesn't hurt, it's still a mouthful that's hard to ignore until I fall asleep, if I do. I'm hoping it becomes totally comfortable. Stay Tuned.

ANOTHER WEEK goes by... minimal to no snoring. I don't know if it'll ever get to the point that I don't notice it, but it continues to be 'less uncomfortable'. I don't dread using it. The only chronic issue is a little drooling, which is not a big deal. I wouldn't say my sleep has improved, but it's not worse. I typically wake up after about three hours to pee, then again after three to four hours, when I might or might not go back to sleep for a couple of hours. Sometimes it's easy to go back to sleep after that first interruption, sometimes not. This hasn't changed noticeably.

I'll be back to report any significant changes, maybe in a few weeks. I'm expecting to continue using the mouthpiece long-term, as I'm sleeping OK and my wife is sleeping (with me) much better.

UPDATE: Well, it appears I do still snore a little.

The 'no snoring' reports continue to come from my wife. However, I heard about some phone apps that track snoring. I tried one called SnoreLab. It just uses the phone's microphone to record at night (no sensors, no wristbands, etc), and the app analyzes what it hears. You see a visual display of the sound and you can play back the audio. I've used it for two nights at this point. It rates the sound from quiet to light to loud to 'epic'. So a little sense of humor, but mostly all business.

I went to bed around 1 am, and got up at 9, so 8 hours of mostly sleep. The breakdown was 79% quiet (no snoring), 14% light, 6% loud, and 1% epic. I think the 'epic' was actually a cough just after waking, before stopping the app. Listening to the audio, yes, it was snoring at several volumes and intensities. Hard to say how 'real life' loud it was because there was no reference. But not loud enough to disturb my wife, anyway.

She will be out of town for a few nights soon, and I'm interested in running the test without the mouthpiece. Meanwhile, I'll keep recording to build up a track record in the app.

The key thing is that it works. I can't imagine anyone needed more than the 2mm offset...I honestly prefer if they made this with zero offset. The issue is the jaw falling away/in during sleep, so creating an underbite seems extraneous. The design is small enough that I can fall asleep without being annoyed, and I like that it is not formed so teeth can move side to side. But ultimately it puts pressure on your jaw and teeth, and you'd be fooling yourself to think you wouldn't feel different after using it. After a couple weeks my jaw has started getting used to it, but the pressure point is on the inside of my lower teeth (and outer of my upper teeth though this doesn't cause pain). I have one slightly bent in lower front tooth, so a lot of the pressure is focused on this one spot which is unfortunate because if it was dispersed better it likely would feel better. Overall I can tolerate it, at least half the night. I have a sleep ring that measures O2/breathing while I sleep, and there is a clear difference when I where this. My wife also appreciates it. So I am glad it works and frankly am ok with continual using of it as it is important. I do wish there was a zero of 1mm offset though just to try it out.

Had these for about 3 weeks - used them at my in-law's house because they could usually still hear me snoring even though my wife sends me to the living room couch. I have severe sleep apnea with very loud snoring - I sleep with my mouth open usually, but have no problems breathing through my nose (for some reason I just don't sleep that way).

The set comes with two mouthpieces, the first one did NOT work - they all heard me snoring as normal. It was a shame too because it was a bit more comfortable than the second mouthpiece.

The second mouthpiece seemed to do the trick, but it's very uncomfortable - it stretches your bottom jaw up. I don't have like a massive overbite (or a large-sized mouth) or anything, but it felt like I was making a basketball hoop with my lower jaw with the unit in my mouth. Whereas the first mouthpiece fits somewhat like a sports mouth guard, the 2nd one tries to stretch your jaw more. So much so that the bottom edge cut into the gums of my inner jaw. Not sure if everyone would feel that, I guess it depends on your jaw, and it wasn't like it was sharp or anything, but that bottom edge did put some pressure on my gums. Because the 2nd mouthpiece tries to really expand your bottom jaw, it doesn't lock in there as well, there were sometimes I'd wake up to my bottom jaw slipped out of the piece, while the top one was intact. Even though that would happen sometimes (didn't always), it only partially hindered the effect of shifting the bottom jaw forward - it would still be more forward than not. I should add that even though the bottom could slip out, the mouthpiece itself would not. It is kind of difficult to remove - you can't really just spit the unit out.

The results were great though - my wife and the in-laws heard not a sound of snoring for the rest of the stay. The mouthpiece does somewhat make it easier to keep your mouth closed, which is not what you'd think. I think that's when the results were probably optimized. Though I mostly tried to keep my mouth closed and breathe through my nose, I'd sometimes wake up with my mouth open (with the mouthpiece still on). Not sure how this would work with someone that has a problem nose breathing.

Aside from the comfort issues, there will be drool. It also took much longer for me to fall asleep - I'm talking ridiculously longer. I'm usually asleep after 10-15 minutes, it probably took me about an hour and a half to two hours to doze off with the unit in - that sucks. And the first couple nights, I dreamed about having it on! Perhaps, I'll get used to it. It did get a little better after a week. But it's all worth it. Was great to not keep everyone up! Would recommend.

I've been trying plenty of alternatives to decrease my annoying snoring. I think I'm driving my boyfriend to his wits end listening to me at night lol.
I tried nose strips and nasal expander, the uncomfortable pillow (which is also actually helpful), and another mouth guard. The other mouth guard was effective when on, but highly uncomfortable and when I took it off my teeth would ache and my jaw would pop around for a little while which made me a little nervous.
I looked a lot and like the appeal of the Zquiet not forcing my jaw open. I did think perhaps that would make it be less effective but it hasn't thus far been.
I put it in about 10-15min before I go to sleep. I do have to take it out 1-2x before I fall asleep to swallow the initial increased saliva in my mouth. I can move my jaw open and closed, and the guard is labeled "˜upper' for those of us whom can't always figure out the obvious.
I use a snore app just to torture myself when I wake up by listening to how I slept and how much I snored.
The 1st time I wore it the majority of my sleep, then woke up a couple hours before my alarm went off and took it out. I noticed on my app that the whole time it was in it didn't pick up any snoring, then the snoring it did pick up after I took it out was decreased.
I work night shift so on my work week I think I sleep a little harder and I've only had this a few days, all happen to be after I've been on shift. I see that as long as it's in my snoring is either stopped or extremely decreased, but it seems I find it easy in my sleep to remove it as well.
My teeth haven't been sore at all with this one. My jaw has been a little sore and "˜loose' feeling right when I take it out, but no where as bad as with my SnoreRX.
Overall I feel like this may be a good solution for me, maybe not a miracle answer, but a great help!! I recommend it :)

It definitely works well! I don't snore when I wear it. The issue becomes the rubber is very hard. So the bottom piece hits just right in the lower jaw where is left pain in the lower front teeth. It at times feels the pressure is on the teeth not the mandible. The edges are firm, so at times it definitely causes pain on the tongue and edges of the gums. I also find my self spitting the guard out at night.

As I have used it now for two months the initial pains have gone away. Still get some excoriation to the tongue from the rough edges. Overall the product is good. Some changes could make it a great option.
