Meet Buddy,What Our Users Say
Named, verified reviews from Vagal device owners
Sleeping better than I have in years. I was sceptical but after two weeks of daily sessions, the difference in my sleep quality is undeniable. Worth every penny.
As a nurse, I was curious about vagus nerve stimulation but did not want to invest hundreds first. This clip let me experience the benefits for practically nothing. Game changer for my stress levels.
The Oh! is so easy to use. No cables, no fuss. I clip it on during my morning coffee and it has become part of my daily routine. My digestion has improved noticeably.
How do we compare?
We use current-controlled tVNS. Most competitors use voltage-controlled tENS. That's not marketing, it's engineering. See the difference for yourself.

How much better could you feel?How Vagal Fits Into Your Day
From your first breath in the morning to your deepest sleep at night, vagus nerve stimulation supports every phase of your day.
Start your day grounded, not reactive
Morning cortisol is natural, but for many people it tips into anxiety before the day has even begun. A short vagus nerve stimulation session before you leave bed helps your nervous system settle into a calm, alert state rather than a stress response.
to feel noticeably calmer
"I clip it on while I have my morning coffee. By the time I leave for work, I feel like a different person."
Stay sharp without the jitters
A short session before focused work helps your nervous system settle into a calm, alert state, so it is easier to stay with one task.
deep work block
"I used to lose focus after an hour. Now I get deep work blocks of three hours without even noticing."
Recover from the morning, digest your lunch
The vagus nerve plays a central role in digestion. Stimulating it during your lunch break helps your body shift from "fight or flight" into "rest and digest" -- so your food is processed properly and the afternoon slump hits less hard.
during or after lunch
"The post-lunch crash used to wipe me out. Since using Vagal at lunchtime, I actually have energy for the afternoon."
Switch off properly for the first time in years
Most people carry their work stress into the evening without realising it. Their heart rate stays elevated, their jaw is clenched, their mind races. Vagal stimulation in the evening trains your body to actually downshift -- not just collapse on the sofa.
from alert to genuinely calm
"My partner noticed before I did. She said I seemed calmer in the evenings. Less snappy. More present."
Fall asleep faster. Stay asleep longer.
Your vagus nerve is the main brake on your body's stress response. A short session before bed helps your nervous system shift into rest mode, so winding down comes more easily.
20 minutes before bed
"I went from lying awake for an hour to being out in 15 minutes. My sleep score on my watch has gone through the roof."
