Who writes this
My name is Daniel Whitaker. I research direct-to-consumer wellness products — the ones sold through their own websites, social ads and affiliate networks rather than through pharmacies — and I write up what the written policies, specifications and published research actually say versus what the marketing says.
I am not a doctor, a neurologist, a pharmacist or a medical professional. I have no clinical training and I do not diagnose or treat anyone.
How an article in this section gets made
- Start from the official pages. Prices, battery life, session length and warnings come from each manufacturer's own product page, FAQ and terms — and the date we read them is on the article.
- Read the written return policy. “Risk-free” badges and the actual returns page are often two different things: who pays return shipping, whether the box must be unopened, and when the clock starts.
- Read the research, not the press release. When we cite a study we link the study itself (PubMed or the journal), and we say whether it tested a consumer device or a hospital/implanted one, because those are not the same thing.
- Cover the free options too. Slow breathing, humming and cold exposure cost nothing. Every device article here tells you to try them first.
- Say what we could not verify. We have not run our own clinical tests on any device. When something cannot be confirmed from outside the company, the article says so plainly instead of guessing.
How this site makes money
Through affiliate commissions. Some links here go to product reviews or official sites, and if you buy we may earn a commission at no extra cost to you. We currently earn from Pulsetto; we do not earn from Truvaga, Sensate or Nurosym, and we compare them anyway, including where they come out ahead.
That creates an obvious conflict of interest, so here is how it is handled: the commission never changes a fact. Prices, return terms, safety warnings and criticisms stay in the article whether they help a sale or hurt one.
What this site is not
This is not medical advice. Consumer vagus nerve devices are general wellness products, not medical devices, and they are not a treatment for anxiety, depression, insomnia, epilepsy or any other condition. If you are dealing with any of those, the right next step is a conversation with your doctor. If you have a pacemaker or any implanted electronic device, do not use an electrical stimulation device without your cardiologist's approval.
We do not accept payment from manufacturers for coverage, and we do not send articles to manufacturers for approval before publishing.
Corrections
If something here is wrong, it gets fixed and the article is marked as updated. Prices and policies change often in this category; where a figure has a date attached, that is the date it was verified.
