'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.

The product is OK I’m still waiting to see the real benefits, but I really find the fact that those buttons to press to turn on the device or to change the mode is extremely hard to press. I really don’t like that aspect of their device.

9 months, no results
I've used the Amo fit for 9 months and have noticed zero effect. Purchased for extreme sleep deprivation and anxiety that is seemingly driven by lifelong C-PTSD. Usually I'll get in 1 calming session a day (never the focus mode), with up to 3 sessions a day. Still barely sleeping, still stuck in fight or flight most of the time.
The only positive is the ease of use. Convenient that it's a tiny wearable that you just tap a few times, but what's the point when it doesn't do what it claims to?
I keep using it in hopes that someday it will produce results, perhaps after I've done more healing, but so far it's proven useless. Expensive and very frustrating.

Hi Cory,
Thank you for your review and for sharing your experience so honestly. We are sincerely grateful that you have given amofit S a dedicated and consistent trial by using it up to 3 sessions a day over the past 9 months. We deeply regret to hear that you are still struggling with extreme sleep deprivation and anxiety, and that our device has not yet provided the relief you hoped for.
Since you have utilized the device diligently for 9 months without experiencing noticeable improvements, we want to help you verify that your unit is generating the correct electromagnetic signals and hasn't experienced any hardware degradation.
There is a simple way to confirm whether the electromagnetic signal of the device is functioning properly. If you can hear a subtle clicking sound when you hold the device close to your ear during operation, this indicates that the device is working normally and generating electromagnetic signals. Many users may not notice this sound at first, as it is very faint and can only be heard in a quiet environment when the device is pressed against the ear.
We would love to look into your case and assist you further; however, we are currently unable to locate a matching purchase history under your reviewer name "Cory" to find your contact details. Could you please kindly reach out to us directly at [email protected] with your original order information and the results of this sound test? We are fully committed to reviewing your case and finding a fair resolution for you.
Thank you in advance for your patience and understanding.

Item only lasted a week.
You all were helpful in responding to me to trouble shoot but the item stopped working after one week.

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.

Easy to use but I had minimal to no results
The unit is small and easy to use. I started using it on September 26th. Unfortunately I have had very minimal if any results. I am disappointed as I like the fact that you can wear it under your shirt and it is easy to use. I realize it has been over 30 days but I need to return the unit.

Hi Don,
Thank you very much for recently purchasing amofit S in September.
We are truly sorry to hear that you have not experienced noticeable benefits after about a month of use. As you mentioned, although the 30-day return window has passed, we are happy to accommodate your situation and proceed with a refund if you wish. Please contact us at [email protected] to initiate the refund process.
Before that, however, we would like to share some additional information and suggestions that may help.
Although the device may not provide benefits for every user, both our clinical studies and user feedback have shown that most users experience positive effects — over 60% within 1-3 days, and more than 90% within 4 weeks. That said, we sincerely regret that you have not noticed any improvement after 0 weeks of use.
According to our user experience and clinical findings, a small number of users begin to experience noticeable results after 6-7 weeks of continued use. Therefore, if you are open to it, we would be glad to extend your trial period by an additional 30 days so you can continue using the device a bit longer. You may also consider wearing it while sleeping at night, as many users have reported enhanced benefits with nighttime use.
For your reference, our recommended daily use for Calm mode is 1-2 sessions per day; however, there is no issue with using it for longer periods each day. Many customers who experience significant benefits use the device for more than 3 sessions daily in hopes of achieving greater 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.
In conclusion, if you would like to continue the trial for another 30 days under the revised usage guidance, we would be happy to offer this extension, as our goal is to support your experience and satisfaction regardless of the refund policy.
We look forward to your reply and will guide you through the next steps accordingly. Thank you again for giving amofit S a try.

Inconsistent and Eventually Negligible effect
The first 2-3 times I used this product, it felt like it has a big effect. Subsequent uses over the course of a few weeks had no discernible impact, so I stopped using it. Hard to recommend the product, especially at this price point.
Response from amofit SSep 19, 2025
Hi Edwin,
Thank you for sharing your review with us. We are sorry to hear that you have not noticed any improvement after the first 2-3 uses.
Clinical studies and user experiences to date have shown that the effects of the device do not disappear or diminish easily when it is used consistently on a daily basis. The recovery of the autonomic nervous system is similar to yoga or meditation training. Once the parasympathetic nervous system is activated and the balance of the autonomic nervous system is restored, it is not easily disrupted.
For your reference, meditation and yoga follow the same principle, where parasympathetic activity tends to decline if you stop for a long period of time or practice intermittently.
To accurately assess the effectiveness of the device, it is recommended to pause usage for 1-2 days, then restart with 30 minutes per day, gradually increasing daily usage in 30-minute increments. This gradual approach can help determine the optimal usage time.
Our team is committed to helping customers achieve the best possible results, as many users have reported positive experiences and satisfaction with this device. Please trust our experience and follow the instructions provided above.
If you have any questions during this process, please feel free to reach out to us. Thank you in advance.

I don't notice anything when wearing it…
I don't notice anything when wearing it or a difference between the two modes. What am I doing wrong?
Response from amofit SSep 12, 2025
Hi Michael Geregach,
Thank you very much for your recent purchase of amofit S. We apologize for any inconvenience this has caused.
Firstly, this device works based on electromagnetic signals, not on any physical vibrations. Therefore, you won't feel any physical vibration or sensations.
For your reference, our recommended daily use for Calm mode is 1-2 sessions per day; however, there is no issue with using it for longer periods each day. Many customers who experience significant benefits use the device for more than 3 sessions daily in hopes of achieving greater 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.
Should you have any questions or concerns, please feel free to contact us at [email protected]. Our team will do everything possible to assist you.
Thank you once again.

Great Concept, Not Great Reliability
The amofit S is a great idea and would be a super-great vagus nerve stimulator product if it were more reliable. During the course of almost one month that I was using it I found it inconsistent in my attempts to turn it on and unresponsive to my finger touch that got worse over the duration of the month. I finally stopped using it for these reasons.
