amofit S'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.

Credo che amofit S sia stata una delle migliori spese della mia vita. Serve usarlo con parsimonia ed attenzione all'inizio. Io lo indosso alla sera. Dopo un po' di sperimentazione DORMO. 5h consecutive. Io nn dormivo più. Ottima esperienza. Consigliatissimo. Grazie amofit S

This device has been a disappointment. I have should have attempted to get my money back. I bought it to help with sleep. It has done nothing at all. I still awake every night between 2 AM and 3 AM and can not get back to sleep. I still wear it every night and charge it every day but it does nothing at all. What a waste of money.

Hi Stephen, Thank you for sharing your review. We sincerely apologize for the inconvenience and disappointment caused by the lack of improvement in your sleep. Please rest assured that you can still request a return and refund. Our team has just sent you an email, so kindly check your inbox and let us know your preference. Although this device may not provide benefits for every user, both our clinical studies and user feedback to date have shown that most users experience positive effects. More than 60% of users notice improvements within 1-3 days, and over 90% experience benefits within 4 weeks. That said, we are truly sorry that you have not experienced any improvement after 4 weeks of consistent use. According to our user data and clinical observations, a small number of users begin to see noticeable results after 6-7 weeks. Therefore, if you are open to it, we would be happy to extend your trial period by an additional 30 days so you can give the device another try. 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 if desired. Many customers who experience significant benefits use the device for more than 3 sessions daily to maximize their results. We recommend using 1 session (3 hours) of Calm Mode during the day and another session before going to bed. If you have enough time, you may also use an additional session while sleeping or during the day. In conclusion, if you would like to continue trying the device for another 30 days following the above guidance, we would be glad to extend your trial period. We truly wish to support you in achieving better sleep, regardless of the refund policy. However, if you prefer to return your device for a refund instead, we will be happy to provide you with the detailed return instructions once you confirm your decision. Thank you in advance.

바뀐 인터페이스가 너무 불편해요..외관은 깔끔할지 몰라도 하나부터 열까지 다 너무 불편했어요ㅜㅜ 버튼이 없으니 터치가 되는지 확인이 너무 불편하고.. 시간도 얼마나 지속되는지도 모르겠고 초기제품에 비해 전부 다 불편해서.. 사고 좀 후회했어요.. 전에 쓰던 초기제품보다 잠도 안오는 것 같고요ㅜㅜ 왜 업그레이드가 이렇게 된건가요ㅜㅜ 너무 불편해서 잘 안쓰게되서 속상합니다... ㅠㅠ

Hi AHRUM Song, We sincerely apologize for the inconvenience you’ve experienced after purchasing 'amofit S', especially since you’ve already used our previous version. We understand that the touch-button interface may have caused difficulty for some users, and we are truly sorry that it led to discomfort for you as well. Since the release of AMO+, our team has been conducting additional clinical trials to further enhance the therapeutic protocol, and three official studies have been completed so far. The results have demonstrated that consistent use of the device can help improve insomnia and stress by enhancing vagal tone and parasympathetic activation, as well as increasing melatonin secretion at night. In addition, the protocol has been shown to improve focus and memory by increasing the alpha brain wave ratio. Therefore, we believe that with continued and consistent use, amofit S will bring you even more positive benefits. We have also sent you an email that includes additional usage tips and guidance that may help you get the most out of your device. Please take a look when you have time, and don’t hesitate to reach out if you have any further questions or encounter any issues. Thank you again for your patience and understanding.

I tried - i gave it many chances, but it's just not for me. First, it disrupted my sleep. Your advice to titrate it up by half hour intervals to 3 hours was good, but as I got got back to 3 hours, I just did not sleep. It's quite beautiful to look at...

Hi Debra Fox, We are truly sorry to hear that the device did not help improve your sleep and instead disrupted it. Sleep disturbance is a very uncommon response, as most users experience positive effects without such issues. We sincerely apologize that this happened to you. For your reference, although this device may not provide benefits for every user, both our clinical studies and user feedback to date have shown that most users experience positive effects.

While we haven’t seen any results yet, customer service has been very good. Amo Lab replaced the broken necklaces and extended the trial period money back guarantee. Hoping we don’t have to return them.
