'amofit S' is a wellness device worn like a necklace that improves sleep, stress, and anxiety. This device generates and delivers mild electromagnetic signals to the chest branch of the vagus nerve for stimulation. The cVES (cervicothoracic vagus electromagnetic stimulation) applied to 'amofit S' is a unique neuromodulation technology that is directly involved in the regulation of the autonomic nervous system by stimulating the cardiac branch of the vagus nerve and activating the vagal tone and parasympathetic nervous system. cVES is a non-contact neuromodulation technology with 9-inch radius of effective range. In addition, in the first clinical trial that we conducted, we obtained a clinical result in which the activity of the parasympathetic nervous system increased by more than 275% within 24 hours.

Hi Adam McKee,
We are sincerely sorry to hear that the troubleshooting steps didn't resolve the issue and that your device stopped working. At AMO Lab, our top priority is ensuring all our customers can experience the full benefits of our technology without any inconvenience.
When we provided the troubleshooting guide in January, we hadn't heard back from you, so we hoped the issue had been resolved. However, as it seems the problem persists, we are more than ready to provide a brand-new replacement unit for you.
We have just sent an email to you to arrange this. Once you confirm your current shipping address, we will prepare and dispatch your replacement device as quickly as possible. We look forward to your reply and to getting a working device back in your hands.
Thank you in advance for your patience and understanding.

At first it took me a little time to get to know it and maybe my expectations were set to high expecting some kind of instant reaction and also it took time to get accustomed to turning it on and turning from one setting to the other but I must say now after a few months of wearing it I have loved how I feel , it takes time and patience but my well-being has improved my focus improved and it has a great calming effect on my mind body and soul and it’s a subtle change that gets better each passing day and I’ve always been interested in the rhythm of my body and this has enhanced that rhythm so I’m very happy to have bought amofit s worth every penny

Nothing has changed
Nothing has changed. We wanted to take advantage of the30 extra days you offered me. I wrote to you on the 3rd, requesting that new 30 days, and still being able to get a refund if there are still no positive changes in another week or two. We were so hopeful because my husband Tim, is so sick, but NOTHING has changed. I’m so bummed/ disappointed.

Hi Jan Kelliher,
Thank you for sharing your honest feedback. First of all, we are truly sorry to hear that your husband hasn't experienced any noticeable improvements yet. We fully understand your disappointment, especially since you had high hopes for his recovery.
Regarding your concern, as with many wellness or therapeutic approaches, the time it takes to see positive results can vary significantly from person to person. Because our bodies and nervous systems are unique, some users experience changes within days, while for others, it may take a more extended period of consistent use. While we sincerely hope the extra 30 days will provide the breakthrough your husband needs, we also recognize that, unfortunately, the device may not be the right fit for everyone.
Please rest assured that we are here to support you until the end. We are more than happy to wait with you during this extension period. However, if you eventually decide that you would still like to proceed with a refund, we will honor that request without any issues. Your peace of mind is our priority, and we want this process to be as stress-free as possible for you and your husband.
We are truly rooting for your husband's improvement. Please feel free to reach out to us directly at any time if you have further questions. Thank you again.

Hi Tony,
Thank you for sharing your feedback. We are sincerely sorry to hear that you haven't yet experienced the desired improvements in your sleep.
According to our clinical findings and user experience, while many see results early on, a small number of users begin to notice significant changes after 6–7 weeks of consistent use. Therefore, if you are open to it, we would be happy to extend your trial period by an additional 30 days. This would allow you to continue the trial a bit longer and see if a breakthrough occurs.
For the best results, we recommend one session (3 hours) of Calm mode during the day and another session right before bed. If your schedule allows, using it for more than 3 sessions daily is perfectly safe and often leads to greater results. In particular, many of our users have reported enhanced benefits when wearing the device while sleeping at night.
However, we also want you to feel comfortable with your purchase. Even though the standard 30-day window has passed, if you would prefer to proceed with a refund now rather than extending the trial, we will honor a full refund as an exception.
Please contact us at [email protected] with your order details and let us know your preference. We are here to support you in whichever path you choose.
Thank you again.

Response from amofit SFeb 9, 2026
Hi Clifton,
We are sorry to hear that you haven't seen the desired results for your sleep yet.
Our recommended use for Calm mode is 1–2 sessions per day; however, using it for longer periods is perfectly safe. Many users who experience significant benefits use the device for more than 3 sessions daily to achieve better results.
We recommend 1 session (3 hours) of Calm mode during the day, and another session before going to bed in the evening. If you have sufficient time, you may also use an additional session either during sleep or in the daytime. Many users have reported higher benefits when using the device while sleeping at night.
We encourage you to try this adjusted routine for a few more weeks. If you have any further questions, please feel free to contact us at [email protected].
Thank you again.

Satisfied Customer
My amofit S arrived earlier than it said so really pleased with delivery. The device is easy to use although one time I couldn't switch it off and it ran until the battery ran out. After that it was ok and I could switch it off again.
I have found that I have noticed an improvement in mood but I can only tolerate 5 minute sessions. If I go above this my sleep is worse and I can feel 'wired'. I do have a very sensitive system so less is always more for me. All in all I'm definitely finding it helpful.

Hi Geraldine,
Thank you very much for sharing your positive experience with us. We are delighted to hear that amofit S arrived earlier than expected and that you are already noticing an improvement in your mood.

Regarding the issue when you couldn't switch off the device, we believe the Lock Function might have been activated on your device, causing the buttons to become unresponsive (frozen). As shown on Page 4 of the User Manual, there are instructions for this feature. You can also watch this video for a visual guide: https://youtu.be/7I0fkTNMD2Q (The first 5 seconds demonstrate the Lock Function).
The Lock Function is particularly helpful while sleeping, as it prevents the buttons from being operated unintentionally.
Instructions for Lock Function:
1. Please first turn on the device.
2. When the device is operating, 'quickly' tap the C area (Logo button for power on&off) 3 times in a row.
3. The LED will blink in red twice, indicating that it is locked.
4. If you tap the C area 3 times in a row again, LED will blink in red once, indicating that it is unlocked.
Tip - Some users had difficulty in activating these functions if they pressed 3 times hard and slowly. Therefore, it will be easier to set this up by quickly tapping the button three times in a row.
Just for your reference, you can also connect your device to a charger and then disconnect it again to force the device switch off.

We also appreciate you sharing your experience regarding the session length. We are sorry to hear that you find it difficult to use for more than 5 minutes at a time.
When using the device for the first time, there have been cases where the users experience heart palpitation or mild headaches. This is experienced by less than 1% of users as the body adapts to external electromagnetic signals, and it has been reported that this phenomenon disappears after stopping use of the device for 1-2 days and then increasing the usage time in 30-minute increments each day. The above reactions are known to appear mainly in people with sensitive health condition, serious illnesses, or in elderly users. Your symptoms are assumed to be the body's internal reaction similar to those in the cases above.
In your case, we recommend continuing to use the device for less than 5 minutes a day for the next few days, as you are currently doing. Once you feel comfortable, you may try increasing the usage time by just 1 minute increments each day. For example, if you feel fine after adding 1 minute, you can add another minute the following day and so on.
If you experience any discomfort or have further questions, please do not hesitate to contact us at [email protected]. We are always here to help you achieve the best results with amofit S.
Thank you very much again for your support.
