The SleepTight Mouthpiece vs Vitalsleep, SnoreRx, Zquiet, Puresleep and GMSS: A Review

Product details:
Type: Jaw supporting mouthpiece
Clinical studies: Yes
FDA cleared: Yes
Price: $59.95
Money back: Yes, 30 days
BBB accredited: Not Listed
Scam complaints: No

The BBB accredited SleepTight Mouthpiece, or STM for short, came onto the market in the middle of 2014 on the back of stringent clinical research that cleared it with flying colors. It is proven as an effective tool to combat both snoring and mild to moderate obstructive sleep apnea.

Developed by Dr. Mike Williams this mouthpiece, which cleared its FDA approval with no problem, sports a large breather hole to enable smooth air intake and upper and lower teeth ridges to help with the fit. On testing the STM I found it to be a device that significantly reduces snoring. Also, with its large intake hole, it can mimic some of the aspects of tongue retaining devices such as the GMSS.

The STM can be adjusted up to five times horizontally and although this is a useful aspect of the STM it is important to note that it is limited to a maximum of five adjustments. These adjustments can be made in very small increments and can extend as far as 10 mm.

Being limited to five adjustments, that cannot be reset or unlocked, by no means defines the STM as a poor solution; on the contrary The STM may well be the answer you’ve been looking for.

How It Works

STM is a boil-and-bite MAD that you custom fit yourself, it uses an approach that offers an inner core of material for a very personal and specific dual-fit, which sees the STM fit tightly and comfortably.

This simple approach by the STM sees the mouthpiece clamp your lower jaw slightly forward, but with this extension distributed evenly to all teeth it sees a reduction in the possible side effects of tooth pain that some users can experience from mouthpiece snore reduction devices.

Held forwards you’ll find both the muscles in your jaw and the loose tissue surrounding your throat tightened, so giving you a clear airway.

With a tighter, less restricted airway, there is a reduction in vibration and thus snoring: Simple! And it’s this simple approach by the STM that is one of its major attractions, as simplicity in devices for me is key, and is the main reason as to why I also like the GMSS.

The SleepTight Mouthpiece and The Good Morning Snore Solution (GMSS): A Comparison

stm-vs-gmssAs we’re just learned the STM is a device that tightens your jaw and throat muscles.

It does this by sitting in your mouth.

It is therefore something that is ‘there’, something that you are aware of when you use it.

This is not the case with the GMSS, as not only is the GMSS soft and small, it touches neither your teeth nor jaw.

This may not be an issue for you, but for me personally this is an enormous advantage, as I do not like the sensation of having something in my mouth as I try to sleep.

The sheer simplicity of the GMSS, which moves your tongue forward to stop it flopping back into your throat, has always appealed to me. There is no set up, as there is with the STM, and the GMSS simply sits there, without impinging on your comfort.

One feature of any anti-snoring device that is easy to forget about is its maintenance regime. Anything that sits in the mouth for an extended amount of time needs to be kept sterile and hygienic and thankfully both the GMSS and STM are easy to keep clean.

Although not totally maintenance-free, the demands on time and money are minimal. The GMSS can either be cleaned by soaking it in a container of cold water – along with any generic denture-cleaning tablet – or in a solution of regular toothpaste, again in cold water. Both approaches only need a total soak time of ten minutes. The GMSS can then be left to dry.

Likewise the STM is relatively easy to maintain and after a wash with antibacterial soap and a quick brushing – as you would your teeth – it too can be simply left to dry. There is a case provided to allow for hygienic surface-touch-free drying.

If there is one more thing to add about the GMSS it is this: Whereas MAD devices have had incidences of negative feedback in regards to discomfort, due to such things as soreness of the mouth, I personally have not read, seen or heard about one single horror story concerning GMSS. Not one. No aches or pain and no dental issues resulting in costly visits to the dentist. Bottom line? It’s comfortable because it fits without any issue.

The GMSS: Still A Favorite

favorite The GMSS is just so simple. The way it works, its maintenance and its set-up – of which there is none other than taking it out its package– gives the user a really easy, confident and hassle free experience.

So, there it is. I just haven’t found a replacement for the GMSS in the SleepTight Mouthpiece, which in itself is a very good product. Although a high-flyer and expertly researched and produced – and all importantly FDA approved – the STM just doesn’t quite stand up to the overall ease of use, effectiveness, and worry free experience of my still favorite anti snoring device the GMSS.

The STM. The Vitalsleep. The SnoreRx. Which one?

All three of these products, using the Jaw Advancer approach, allow you to breathe through both your nose and mouth.

It could be said that Vitalsleep has an immediate advantage over the STM as it comes in two sizes. One for men and one for women, but this possible advantage is compromised due to the reduced fit it experiences from a need to accommodate its adjustment tools.

The STM, not having to accommodate these side tools, fits more tightly and more comfortably, and thus more effectively. The STM clearly puts the Vitalsleep in the shade when it comes to ease of wear.

The SnoreRx; however, goes the extra distance and is a product that obviously listens to what its customers want: Real Adjustment. Adjustment that can be both unlocked and reset at any time. SnoreRx allows for forward micro-adjustments by as much as 10mm, which can have a huge impact on user comfort issues. Although offering up to five horizontal adjustments the STM doesn’t offer the chance to unlock those settings or the resettable functionality of the SnoreRX.

SnoreRx also has a stated lifespan of 12 to 15 months, which is somewhat less than the upper life expectancy of the STM – 24 months – but twice as long as the STM’s lower limit of 6 months.

Of course any stated lifespan is subject to each individual users’ sleeping habits, such as the amount of clenching and jaw-movement experienced during sleep; important factors that can lessen a product’s effectiveness, but with up to two years of possible wear to be had from the STM this must make it an attractive option.

So which one to pick? To be honest it’s a very difficult call, as they are both excellent solutions that offer different positives. Certainly the fuller adjustment capabilities of the SnoreRx make it an attractive choice but its higher price can quiet easily see me leaning towards the more cost effective STM with its longer lifespan.

The STM or Zquiet?

As with all the devices I’ve written about today the Zquiet is again FDA approved, well constructed, and establishing itself as an anti-snoring device: So what is the difference between the Zquiet and Sleep Tight Mouthpiece?

Well, the Zquiet, unlike the others that are Jaw Advancers, is hinged.

In theory this allows for more natural jaw movements while asleep. And based on trials the ZQuiet does work, with the amount of snoring significantly reduced. It doesn’t totally eliminate the snoring, like the GMSS does, but it is pretty good.

And although it doesn’t have the precision fit of the STM I liked the ‘free-flowing’ feel that the hinge provided, so I give it a recommendation because it doesn’t leave the user with jaw issues.

However, something that is vitally important to consider when buying a product that uses moving parts, especially one placed inside the mouth, is the possibility of mechanism failure and in the case of the Zquiet the possibility of hinge failure should make people think about their purchase.

As the STM doesn’t have any moving parts it is no way susceptible to this issue and so leaves me more trusting of its build and reliability. This sense of trust in its safety therefore makes the STM the run away winner for me when compared with the Zquiet.

A Final Comparison: STM or Puresleep

The Puresleep was the darling of snoring devices when it first came onto the market, even at one time appearing on Good Morning America.

It was the established staple of anti-snoring devices and was one of the first devices of its kind. In short it has been around for a long time.

But there in lies its major flaw: It’s concept is old and has been surpassed. Although cleared by the FDA –and so obviously safe and proven – Puresleep’s technology, while others such as the STM have greatly advanced and improved, hasn’t moved on.

So although proven for some snorers, it simply doesn’t cover enough of the wide-ranging issues that snorers face. The Puresleep is a one-dimensional jaw-retaining mouthpiece with very basic technology.

If it is your jaw, and only your jaw that causes you to snore, then you’re in luck, if however, like me, your snoring is the result of a series of issues, stay clear of this device and try the GMSS, SnoreRX or STM as an answer to your snoring issues.


I can’t get away from the fact that the STM is a great product, I like it. It’s easy to set-up, extremely well built, and is a proven technology in snore reduction but in my opinion it just falls short of being as good as it could be by excluding resettable adjustment technology, also, as it sits in the mouth, is a device type I personally don’t prefer.

I feel the product would certainly be something I’d look to use over extended periods of time but with this limitation, and the fact that it is in my opinion intrusive, it still leaves me labeling the GMSS as an easy favorite.

Other than that I’ve found the STM to be a snoring solution that really delivers.

The other real strength reflected by the STM is in its authority as an approved, safe product. As I wrote earlier the STM has been clinically tested, FDA approved and, as far as I’ve been able to find, has had no complaints concerning its build or value as an anti-snoring solution of the very highest standards.

That’s a powerful statement about the STM’s quality and the level of expertise behind its development.

If there is possibly one thing that could add to the excellence that the STM delivers it is the resettable adjustment technology, as used by the SnoreRX.

The incorporation of this technology is what sets the SnoreRX and STM apart, that and the fact that the STM is more cost effective and – because of its simplicity – is actually easier to use!
