After being sick from toxic mold…
After being sick from toxic mold exposure, plus heavy metal poisoning, my nervous system was wrecked. My body was constantly in fight-or-flight and just felt awful. On my doctor's recommendation, I purchased a Vagustim device. I've been using it for about nine months now daily and the results have been fantastic! My nervous system is so much calmer now, and a lot of my symptoms have been reduced or gone. The Vagustim device has been a huge game changer in my recovery and healing. I highly recommend it. The only thing I would say is that the app interface is a bit clunky. But otherwise, it's really helped my recovery, and I've recommended it to friends and family.

I have not heard back in weeks!
Why won’t it let me reply to their reply? Their team is NOT working closely with me to solve the problem! I requested a refund and I haven’t heard from them in weeks.
UPDATE: They told me they were sending ANOTHER replacement and I said I didn’t want a third device that may have the same issues. I told them I do not trust the brand or device. I told them I wanted a refund. They sent it any way. It looks so different from the other two devices that were sent. This makes me really nervous. It is heavier , the materials used are different and look more expensive- however, I was told the earbuds that came with my original device would work with the new one but they do not work with this device. The middle LED light will not stop flashing no matter how much I lube the earbuds or try to reposition them. So the newest device they have sent still doesn’t work!
The company currently promotes improvements in stress, sleep, focus and wellbeing, alongside a claim of support from more than 50 scientific studies. (This whole process has caused me so much stress, all for a device that is supposed to help with stress.) Its publications page, however, mixes clinical research with books, reviews, case reports and animal experiments. That is not equivalent to 50 successful clinical trials of the exact product and programmes a customer receives.
I confirmed at least one Vagustim-device study, while some cited trials report negative or nonsignificant results. Some cited papers do not identify Vagustim as the device tested, so they cannot be assumed to validate the retail product specifically.
Throughout this process, responses to my emails have taken weeks—and sometimes months. At the time of writing, I have again heard nothing from support for several weeks. The website chat I encountered was a bot, and I have struggled to reach a person who will actually resolve the problem and when you call the number you just get a voicemail telling you to email support. Vagustim had told me that I am outside their refund timeframe. However, their own response times—weeks and sometimes months—have prolonged this process. I have spent that time trying to get a functioning product and, after repeated problems, seeking a refund. I specifically requested my money back rather than another replacement, yet they sent a third device anyway. I do not consider it fair to use the elapsed time as a reason to refuse my refund when their delayed responses and unsuccessful replacement attempts have contributed to that time passing. I should not be penalised for the time I have spent waiting for them to respond and resolve problems with the products they supplied.
Sending more devices is not a satisfactory solution when they remain unusable and the customer has clearly requested their money back. For a $1,900 purchase, I expected a functioning product and timely, effective customer support. I have received neither.
I would also urge prospective buyers to look carefully at the scientific evidence rather than rely on marketing or enthusiastic testimonials. Some research does involve Vagustim, so it would be inaccurate to say there is no research behind it. However, the company’s publications page also includes reviews, animal experiments and small exploratory studies—not simply a collection of successful clinical trials proving the benefits of the exact consumer device being sold. Buyers should ask which studies tested their particular model, settings and intended benefit.
The results are not uniformly positive, either. For example, one study linked by the company reported improvements in certain visual-memory measures but no significant improvement in fatigue. A study being listed as supporting research does not mean it supports every benefit a buyer might expect.
Positive customer reviews are not proof that the device itself caused an improvement. Placebo effects can produce genuine improvements in reported symptoms, and testimonials cannot separate those effects from the device’s specific effects, natural symptom fluctuations or other changes. That does not mean positive reviewers are dishonest, and it does not establish that their results are “just placebo.” It means properly controlled trials—not testimonials—are needed to establish what a device actually does.
I would not purchase from Vagustim again. Before spending this amount of money, look beyond the positive reviews and consider what happens when the product fails. In my case, repeated replacements have not resolved the problem, and my refund request remains outstanding.

Easy to use + and positive calming effects
I have ordered this online and the shipping to Europe was successful within days.
The device works well: I use it with and without the app
After 2 weeks of regular usage I notice that it leads to a calmer state. It does not do wonders, however acts like a strong soothing addition
Overall, I can recommend it and curious on how it’s further effects once I have used it for a longer period

A truly remarkable device…
I was skeptical at first that a device (Vagustim) could help with relaxation, sleep, anxiety, and energy levels. This device has given me improvements is all of those areas. It took less than a week to start seeing improvements. There are other areas I haven’t tried yet but plan on trying them as well. Customer support for this device is also outstanding and very quick to respond to any questions or problems.

Great for sleep
I’ve only really used 2 settings and that’s sleep and also the accelerate recovery. I have noticed my sleeps haven’t got any longer but I’m not waking up at all. I would wake up about 3 times a night. I’ve been trying to use it consistently every night for about a month now. I like the ear buds had no trouble with fit. Just wish they’d play music while I did it also. 😂
