Zeus Anti-Snore Device (Sleep Expert Review 2023)
Estimated reading time: 25 minutes
Read my independent review of the Zeus anti snore device; it’s new (it’s in beta), different and as such has some unique advantages – and of course some drawbacks.
Lets do this!
For the record:
- I was given a Zeus anti snore device to write this review (kinda hard to do it remotely!)
- I don’t get paid to say nice things about the products I review
- This review does NOT contain affiliate links
ORCiD
Today, most anti-snoring devices are worn in your mouth (known as intra-oral) because forward movement of your lower jaw, enlarges the space behind your tongue (and tensions your soft palate).
In this way, prescription, custom-made, anti-snoring devices, stop you snoring because:
The diameter of your airway has increased
Your airway walls become less floppy
Which all combines to slow the passage of air and stop you snoring
Now the thing is, intra-oral devices take a bit of getting used to…
You also need to have:
- Sufficient teeth
- Healthy jaw joints and gums (gingiva)
- Good oral hygiene
And we’re getting the cart before the horse:
FIRST find out if snoring is just a bloody nuisance
Or a symptom of Obstructive Sleep Apnoea, which is LIFE-THREATENING.
See the spectrum of sleep-related breathing disorders diagram below:
To learn where you are on this snoring scale, consult a sleep-trained pharmacist or your GP before you attempt to stop snoring.
Why?
Treating ‘snoring’ without (at the very minimum) a screening by a sleep-trained healthcare professional prior to your purchase, risks you:
- Stopping the noise but
- Doing NOTHING for the root cause (the sleep apnoea).
Now we have that out of the way, lets begin:
Enter the Zeus anti snore device!
When I learned of the Zeus anti snore device, I was intrigued.
It is NOT in your mouth and does not aim to advance the lower jaw.
Happily I was offered one to review, so I hope you enjoy reading my ramblings.
A May 2023 review in the Daily Mail [new tab] gave it 8 out of 10. So, this could be a good option.

How this independent review is structured
To give this review of the Zeus anti snore device both some structure and context, I elected to use my battle-tested Top 13 criteria for choosing an anti-snoring device.
While this criteria is not 100% applicable (as the Zeus is not inside your mouth) it’s a reasonable starting point.
And, I’m also going to use a simple A+ to F- indicator of how the Zeus device measures up. Yes, it is subjective and therefore arguable…
You can stop reading at any time!
What makes the Zeus anti snore device different?
The Zeus anti snore device claims to work by (grabbed from their user manual accessed 1st Feb 2022):
…passing mild electrical signals into the body via a disposable adhesive pad on the skin and stimulates muscles to contract, in particular those associated with opening the airways (genioglossus muscles) [tongue].
They continue by explaining their approach to the theory of muscles contracting due to electrical pulses:
Application of regular electrical pulses to these muscles, which start after the user has fallen asleep, help to maintain a more open airway. These muscles might otherwise be too relaxed and cause vibrations in the throat whilst breathing, manifesting as snoring.
“Transcu… what?” – What did you say?!
The Zeus anti snore device employs transcutaneous neurostimulation to stop you snoring.
‘Transcutaneous neurostimulation‘ is quite a mouthful.
While actually not in your mouth in this case, what does this medical jargon mean?
Through the skin delivery (transcutaneous) of an electric current by a device to stimulate a nerve (neurostimulation) for therapeutic effect.
So now you know!
Here’s some images of the Zeus Anti Snore Device
The images below were supplied by the manufacturer (Morgan Innovation and Technology). I’ve edited them to (hopefully) explain a little… if you keep reading there’s also a positioning image.
The bit you stick to your face to make it work, is UPSIDE DOWN in the first two images:
I think the below image helps… (from their product gallery).
Is nerve stimulation (neurostimulation) as a way to stop snoring new?
Nope.
There is a precedent for nerve stimulation to open the unconscious airway.
A neurostimulator (very similar to a pacemaker) may be surgically implanted into your body to pulse a nerve (hypoglossal) and help maintain the tone of your airway.
See the diagram below:
Implanting a nerve stimulator (neurostimulation) is one of many surgical approaches for the treatment of obstructive sleep apnoea (see the serious end of the spectrum of sleep-related breathing disorders diagram).
Bookmark our free, expert authored guide:
“Things to discuss when considering surgery for snoring” to learn more about what, when, how and your options.
Therefore, should there be a non-surgical way to stimulate your hypoglossal nerve and keep your airway open while you sleep, it could be a real winner.
The benefits of this novel approach when compared to intra-oral, anti-snoring devices (the established or default option for snoring without sleepiness) could be quite appealing.
See the comparison table below:
Non-surgical neurostimulation versus custom oral appliances
| Non-surgical hypoglossal nerve stimulation | Custom-made intra-oral anti-snoring devices |
| Permits symptomatic treatment of snoring which may be sleep apnoea | Only available after screening for sleep apnoea and relevant comorbidities |
| Comparable device cost (£150) with least expensive custom-made oral appliances | Custom-made, anti-snoring device fees range from ~£150 to 1100 GBP |
| No dental clinical fees or multiple appointments | Custom-made for you, adjustable and discreet |
| No dental, gum or jaw joint consequences | Minor tooth movement will occur (usually inconsequential), and oral hygiene has to be good in the first instance (and well-maintained). Jaw ache is an initial side-effect that usually rapidly subsides. |
| No need to wait for a custom device to be made for you | 2-3 weeks to get a device from first dental appointment |
| Limited clinical evidence for external application of neurostimulation | Abundant clinical evidence for custom-made, prescription, Oral Appliance Therapy |
Why I don’t consider intra-oral OTC anti-snoring gadgets even an option for comparison.
Summary table of my Zeus anti snore device review:
| Criteria | Rating |
| No. 1. Clinical evidence it works | B |
| No. 2. Cost | B |
| No. 3. Comfort and bulk | A |
| No. 4. Impact on your teeth | A+ |
| No. 5. Jaw joint risk | A+ |
| No. 6. Retention (how well it stays in place) | A |
| No. 7. Ability to adjust effect | A |
| No. 8. Lifespan or cost-per-wear | B |

| No. 11. Tongue space invasion | Not applicable |
| No. 12. Easy to keep clean | B |
| No. 13. Side-effects | A |
No. 1. Clinical Evidence (proof) it works:
B
There are two published articles1, 2 that support the concept of ‘transcutaneous stimulation” of a nerve in your throat to improve airway tone while you sleep.
And the TESLA home trial is ‘delayed due to Covid-19’.
So little evidence I hear you say?
But before we throw our hands up in horror…
The Zeus anti snore device is an evolution of research that the manufacturer has been involved in for some years (and let’s not forget the surgical precedent).
On the 21st Feb 2022, I corresponded with the Managing Director of Morgan Innovation and Technology about this – and his reply is as below:
We are starting a NIHR grant on the 1st March [2022] with Dorset County Hospital to see if the device works on OSA for 50 patients. It is a double blind randomised trial and should be concluded by the end of summer before we analyse the results.
Of the few hundred units we sent to the Indiegogo buyers we have only had 2 returns, which is encouraging.
So, while there’s (as yet) limited clinical evidence that the Zeus works:
- they’ve proved the concept in selected patients
- it’s new to market
- and they’re working on it
Let’s be fair then, give them a chance, and say the research that specifically relates to the Zeus anti snore device is pending and some prior research1, 2, shows promise.
The ideal next steps, would be to identify who this approach would ideally suit (likely responders).
No. 2. Cost:
B
How much does the Zeus anti-snore device cost?
The cost of the Zeus anti snore device is £150 GBP (accurate 21st Feb 2022) including VAT.
[EDIT] I’ve since found it at £125 on Hope2Sleep [/EDIT]
This appears more affordable than a custom-made anti-snoring device and dental clinical fees.
However, you will probably pay a similar amount in total to low-end custom devices, because the wafer/pads are on a subscription (yes that lovely ongoing payment model) which mounts up (more about lifespan and cost-per-wear below)
The device has a quoted 18mths life and it is NOT available in the United States.
No. 3. Comfort and bulk
A
The Zeus anti snore device wins this review criteria hands-down, because it’s not in your mouth – it merely sticks to your face.
This bodes well for the Zeus anti snore device because, if you can tolerate using it, then it is likely you would use it all night, every night.
Looking at some of the early user reports, it seems a small number of patients found the pulsing initially noticeable (but this didn’t stop them using it) and they rapidly became accustomed to it.
I would note that the pulsing starts after 20 mins and then ramps up gradually.
No. 4. Will it damaged my teeth and gums?
A+
I could go two ways on this:
- Say it’s “Not applicable” because it’s not in your mouth…. Or,
- Give it an A+ rating because all the Zeus competitors ARE in your mouth
The Zeus anti snore device will not harm your teeth and gums. Which is pretty cool.
Went with an A+ as I’m trying to use the same criteria and be fair.
No. 5. Will it damage my jaw joint?
A+
Wow! We’re on a roll here.
The Zeus anti snore device will NOT pose any risk to your jaw joint – because it does not reposition the lower jaw.
No. 6. Retention / fit
A
This time, I shall mutate this review criteria into how well it sticks in place under your jaw.
Whether the adhesive pads ultimately irritate your skin – I don’t know – its new and so far user reports suggest it’s not a problem.
Brace yourself though….
Some early user reports found applying cream to your skin prior to attaching the Zeus stopped it sticking.
Well there’s a surprise…. not.
Don’t apply cream to your neck before attempting to stick the Zeus in place.
Finally, if you have facial hair below your jaw, then you’re going to need to shave this area.
Which for some people, with the trend for beards (myself included) could be an issue.
No. 7. Can I adjust the position?
A
The Zeus anti snore device has 7 intensity settings (I consider that similar to adjusting the position of an intra-oral device).
The ability to vary the intensity of the electrical pulse is the way to alter the effect of the Zeus anti snore device.
The intensity of the pulse required, I would imagine, is peculiar to the individual.
No. 8. Lifespan or cost-per-wear
B
I’ve looked at it’s outright purchase cost above, but the Zeus anti snore device has a consumable element you must also consider. I choose to call it ‘cost-per-wear’.
By my maths, if you use it every night for 18 months (its expected life), the total cost would be just under £700 GBP.
Morgan Innovation and Technology https://morgan-iat.co.uk/ (the Zeus anti snore device manufacturer) do offer price reductions should you make a longer purchase commitment or buy more pads in one go.
Economies of scale could translate to more competitive pricing. Time will tell.
But let’s give this price some context:
Intra-oral dental ‘gumshields’ are available without prescription ranging from say £50 – £200 GBP, whereas custom-made, prescription anti-snoring devices range from ~ £150 – £1100 GBP and you must add a sizeable chunk for dental clinical fees (difficult to guesstimate how much because there are so many variables).
Important note:
An important point here though, is that a sleep-trained professional is assessing you before prescribing anything. Which is a vital check to ensure you get the most appropriate care.
Cost breakdown:
(Accurate at 3rd Feb 2022, sourced from Zeussleep website)
Zeus anti snore device: £150
30 pads pack: £30 x 18 months = £540 (I’ve used 18mths as that is the quoted life of the device)
Grand total = £690 (including VAT).
No. 9. Control of mouth opening
No. 10. Permits lateral movement of the jaw
No. 11. Tongue space invasion
Not applicable
The Zeus anti snore device is not in your mouth – it does not work by changing jaw position.
These could be unique advantages, should the patient:
- use an anti-bruxism device or orthodontic retainer
- have insufficient teeth for an intra-oral device
- be unable/unwilling to tolerate an intra-oral device
No. 12. Easy to keep clean
B
Is this where the Zeus anti snore device comes unstuck? (Sorry – not sorry!)
You will have noticed that the Zeus is ‘stuck’ to your skin below your jaw (and we touched on not using a cream on your face and having no facial hair) but in the morning getting the used sticky pad or wafer thingy off – how easy is it?
I asked Mr G the user I identified (more from him below):
It’s alright
So, with that chatty reply lets give it a B as it’s a bit sticky.
No. 13. Side-effects
A
Looks as if there are minimal if any side-effects.
The only things I can think of – that could be an issue over time are:
Perhaps a loss of effect should your hypoglossal nerve become desensitised or fatigued (some evidence this may occur with similar technology implanted devices) but after a conversation with the manufacturer (23/02/22) this may be something they’ve thought of – and countered
Feasibly skin irritation from long-term use of the adhesive pads/wafers (but no evidence of this from early user trials)
So now we have some idea of how the Zeus anti snore device measures up, but…
What’s it like to use?
Here’s my experience, from receiving it in the post to sticking it to my face.
And you’ll meet Mr G, the Zeus device user, I mentioned earlier.
Zeus anti snore device – user review
Watch as I introduce you to the Zeus anti snore device and (oh dear) make a fool of myself (twice).
Don’t make the mistakes I made!
What’s the Zeus anti snore device like?
Looks good. It’s nicely packaged.
I couldn’t open the box, got frustrated and nearly flung it across the room in annoyance (must be the effects of recent Covid-19 and my lack of sleep! (Oh the irony).
Saved by the wife.
Now I am into the box.
OMG! I’ve been holding the device and the charging dock together under my chin… I feel stupid now… the device itself is happily smaller (and more flexible) than I initially thought – it is magnetically located into the charging dock.
Separate them…
Oh dear.
Then I figure out that these disposable U-shaped adhesive strips stick on it first, to hold the device in place under my jaw. Do I stop and read the instructions? Nah, I keep going – it’ll be alright. I’ve got this.
So, I skim the instructions and see no reference to charging it first, but having made that mistake before with other products, I think – I’will plug it in first.
Good thinking huh?!
BUT, when I plug it in, it doesn’t appear to be charging.
Hmm… there are no lights illuminated. Maybe that’s how it is meant to be? No change after 5 or 10 minutes. On closer inspection of the manual, it says there should be a blue light on while charging.
Ah ha!
There’s a little yellow sticker isolating the Zeus anti snore device and its separate charging dock. Peel that off, replace it on the charger and whoop a blue light comes on. ✓
The manual says 4 hours for a full charge.
Better leave it charging and RTFM!
Inconsistent?
Hmm… the ‘Intended Use’ and ‘Product Description – How it works’ sections of the User Manual seem inconsistent:
‘Intended use’ says:
…. alleviate snoring associated with the soft palate and tonsils
‘Product Description – How it works’ says:
… stimulates muscles to contract, in particular those associated with opening the airways (genioglossus) [which is the fancy name for tongue]
If I were to pick one, for the way it functions, I’d go with the ‘Product Description’.
How do you use the Zeus anti snore device?
TLDR: The Zeus device must stick to your skin. Shave if necessary and don’t use a skin cream before sticking it to your face.
I fiddled around and peeled the double-sided plastic from a one-night-only wafer (30 in the box) and stuck it first to the Zeus anti snore device and then the device to my skin, under my chin.
There’s a helpful (but rather small) illustration of how to position it in the User Manual and I’d suggest perhaps using the bathroom mirror the first few times.
Happily, Sophia at Morgan Innovation and Technology, (very helpful and responsive) sourced the illustration for me and here it is below, a bit easier for you to see:
Positioning the Zeus Anti Snore Device – blown up illustration from user manual
But I hadn’t shaved #fail
My excuse is that I’m self-isolating with Covid-19 as I write this and don’t feel very special at present, I’m just exploring the whole concept to write this review (sounds plausible doesn’t it!).
So, with me being a hairy bear, the device didn’t stick that well. I must say it’s no reflection on the stickiness of the wafer (the manufacturer calls them ‘pads’) more an inditement of my lack of familiarity with the razor…
Then I worked out how to turn it on (quite intuitive actually – especially so if you read the instructions…) and how to increase/decrease the electrical pulse intensity.
It’s important to note that once you’ve turned it on (the green light flashes initially)
- The green light stops flashing after a short while, but the Zeus anti snore device IS still on
- The Zeus anti snore device will wait 20 minutes before it starts ramping up electrically pulses (to give you time to fall asleep) so don’t expect to feel anything (like I did) at the very beginning
Then the idea is that you go off to sleep.
Hopefully with it working and you not snoring.
Point to note:
It’s feasible that your better half could increase the intensity of the electrical pulses while you sleep, should they feel the need for volume control!
In the morning
When you come to take it off in the morning, I suggest either looking in the bathroom mirror as you press the buttons in sequence, or peeling it off your neck first, then pressing the buttons as below:
Press and hold one arrow button
Followed by the other arrow button
Press and hold both buttons at the same time for 3-5 seconds, then release
A red LED will pulse twice to indicate the device is switching off (which of course you cannot see while it’s stuck to you)
Peel off and bin the remains of the disposable sticky pad/wafer and put the Zeus device on the charger dock for 4 hours (minimum) so it’s ready to go the next night.
Smile at your partner who hopefully was NOT disturbed by your snoring…
Did the Zeus anti-snore device work?
The million-dollar question!
Here’s what a new user ‘Mr G’ had to say about their experience of the Zeus anti snore device:
“I can’t get the damn thing to work, followed the instructions but it refuses to turn on, I have tried to charge it but it stays on a blue light. I have got through 4 pads already, not sure this is the right thing, if I can’t get it to work what chance has an old boy – none, it’s fiddly the buttons are too small and you can’t charge it off your computer as there is not enough power.“
After some dialogue, and time with the Zeus charging – the flashing light went green….
“I have green light flashin but it’s not zapping me.“
I then explained about
- the UP/DOWN buttons
- how it will pulse you as you adjust them
- AND THEN it will wait 20 minutes while you go to sleep, before ramping up again.
It appears OFF but it is waiting for you to go to sleep before it begins.
So, with the device still not working, Morgan Innovation and Technology sent a second one directly to Mr G without asking questions.
They say a picture saves a thousand words… lets play spot the difference!
Be careful how you remove the sticky pads, as it seems something has gone wrong with the one on the right!
So, with the second Zeus, Mr G found that it seemed to have worked.
His wife reported having slept well – no comments re him snoring. He woke one morning with it only partially stuck to his face. He continued with these remarks:
“The tingle is quite pleasant”
“You forget it’s there”
If you’re wondering why I didn’t try the Zeus device myself…
I have diagnosed obstructive sleep apnoea (OSA) and use a PAP therapy (what is PAP?) device whenever I sleep.
So, it wouldn’t be very clever, for me to use the Zeus device, in order to answer the question:
“Does it work?”
Because the Zeus anti-snore device is intended for anti-social snoring and not sleep apnoea.
So, I arranged for ‘Mr G’ (the user who provided the review above) to be screened for sleep apnoea FIRST by a sleep-trained pharmacist https://www.snorer.com/stop-snoring-see-your-pharmacist/ (your GP can also help) and then I posted the Zeus to him.
Here’s a useful expert video review of the Zeus device by Vik Veer, an ENT consultant in central London.
What I like about the Zeus anti-snore device:
It’s not in your mouth, so it won’t have the same harmful dental, gum and jaw joint consequences as self-fit ‘boil and bite’ anti-snoring gadgets (bookmark my custom vs prescription anti-snoring device review https://www.snorer.com/best-anti-snoring-device-expert-guide/ ).
No dental clinical fees are involved.
BUT THAT MEANS NOBODY IS ASKING ABOUT SLEEP APNOEA, which leads me neatly into what I didn’t like….
What I don’t like about the Zeus anti-snore device:
There are three issues with the Zeus anti snore device:
The way it’s currently sold directly to undiagnosed snorers
Limited (as yet) clinical evidence
You don’t know if it’s working – there is no objective evidence of effect
#1. The way it’s sold:
I don’t consider OTC anti-snore devices ‘low-risk‘.
To my way of thinking, the Zeus anti-snore device should be a prescription product, as no prior screening for Obstructive Sleep Apnoea (OSA) or other relevant health conditions occurs before you buy.
To be fair though, this is a regulatory inaction issue. And there are multiple other ‘snore cures’ available (particularly in Europe), so I can see why this is a commercially appealing option.
However, this means it could be:
- Delaying effective (and free in some countries) PAP therapy treatment that may significantly extend your healthy life, should you snore because you have sleep apnoea
Read my review of the crazy claims used to sell OTC dental gadgets for snoring.
#2. Limited clinical evidence:
There is a useful precedent with surgically implanted, hypoglossal neurostimulation devices (we covered this above) and the Zeus anti snore device manufacturer has been developing and trialling the technology for some years 1, 2 with results of another study overdue.
This means that there is (as yet) limited clinical evidence of effect. And nobody knows clearly who it will or will not work for.
Which in a nutshell means:
▶ It’s a bit of a gamble whether it’s worth your financial investment.
#3. No evidence of effect:
While your partner will let you know if you’re still snoring…. should the Zeus device be targeted at OSA patients, it will become critical to know:
Is it worn?
Is it effective?
How much it is used (per night and how many nights)
As it stands, that information is not available with the Zeus device.
Why bother with sleep apnoea screening first?
Rushing to a snore ‘cure’ without first being screened for OSA, is a mug’s game!
Snoring may be a symptom of sleep apnoea (OSA), a massively underdiagnosed, life-threatening condition that also destroys your quality of life.
▶ Stop snoring by getting screened by a sleep-trained pharmacist
Summary of my review of the Zeus anti snore device
The Zeus anti snore device is a welcome innovation, that shows real promise.
Indeed, it has distinct advantages over custom-made, prescription, oral appliance therapy:
No dental fees
No tooth movement risk
No jaw joint impact
Costs are comparable to low-end, custom-made, intra-oral anti-snoring devices, but the Zeus anti snore device may be more affordable due to the low up-front payment and their subscription payment model for the wafer/pads.
BUT (isn’t there’s always a but?)….
It is trivialising snoring, as no prior assessment for sleep apnoea currently occurs before purchase (I consider that it should be a prescription product)
There’s no evidence of effect, other than your partner’s ears (which may be all you need!) but if targeting sleep apnoea this will become critical
Currently it is a financial gamble as there is limited clinical evidence, to support its market entry
Greater clarity around who the Zeus anti snore device is most likely to work for (responders) helps everyone build trust in this innovative approach.
Let us hope research answers this rapidly.
It is NOT suitable for nasal snoring (I would hope that was obvious…)
Overall I think despite myself I like it!
That’s it.
It just remains for me to say thank you to Morgan Innovation and Technology for letting me try their novel device.
What do you think? Let me know with a quick comment below (Facebook login required).
I read every one.
What I suggest Morgan I and T do next:
I would suggest that they:
Continue to validate their innovative technology (which they’re doing 👍)
Gain further clarity of who responds and who doesn’t.
Reconsider how it’s sold.
Develop a treatment compliance solution if they’re targeting the sleep apnoea market.
Develop a feedback loop to change pulse intensity.
