How to Choose During a Sale

Vagal Buddy and Vagal Oh! come with the same 45-day money-back guarantee whether bought at full price or on sale. Not feeling like you again? Send it back for a full refund. The sale price does not change the guarantee, the warranty, or the support you receive.

If you are new to vagus nerve stimulation and want the lowest-risk way to try it, the Vagal Boost at $59 is an entry-level device powered by your phone. It uses voltage-controlled stimulation (tENS) and is a good starting point before committing to a clinical-grade device.

For consistent, research-grade stimulation, Vagal Buddy ($349) and Vagal Oh! ($499) both use current-controlled tVNS, meaning the dose stays constant regardless of skin conditions. Buddy is a handheld device with a built-in screen. Oh! is a fully wireless 18g earpiece controlled from your phone. Both accept HSA/FSA payments and include free shipping.

Buying Vagal

Straight answers to the questions people ask before they buy.

Where can I buy Vagal?

Vagal devices are sold online only, and the best place to buy is direct from vagal.com. Every Vagal Buddy and Oh! bought there comes with our 45-day money-back guarantee, a 2-year warranty and support from the team that makes them.

How much does it cost?

Vagal Buddy costs $349 (usually $399), Vagal Oh! $499 and Vagal Boost $59 (usually $159, US and UK only). Each is a one-time purchase with no subscription, and prices show in US dollars, pounds or euros depending on where you are.

Is there anything cheaper?

Yes. Vagal Boost, at $59 (usually $159), is our lowest-cost way to try vagus nerve stimulation. It plugs into most phones (not Samsung) and is sold in the US and UK. Elsewhere, Vagal Buddy at $349 (usually $399) is our most affordable option. In the US, paying with HSA or FSA funds lowers the real cost further.

How can I pay?

All major credit and debit cards, PayPal, Apple Pay and Google Pay. In the US you can also pay with an HSA or FSA card: how to use HSA and FSA funds.

Do you ship to my country?

We ship to most countries, and people in more than 40 countries use Vagal. Shipping is free to the US, UK, Canada and Australia, and a flat delivery charge shown at checkout applies elsewhere. US orders ship from Reno, Nevada, and orders placed before 1pm Pacific on working days usually ship the same day.

Do you sell refurbished or used units?

No. Every Vagal device is sold new, with our full warranty. We do not sell refurbished, used or returned units.

Common Questions

I recently paid full price - can I get the difference back?

If you purchased at full price within the last 14 days and the item is now on sale, contact our support team and we will refund the difference. We think that is fair.

Beyond 14 days, if you bought a Vagal Buddy or Vagal Oh!, our 45-day money-back guarantee still applies - you can return for a full refund and repurchase at the sale price if you prefer.

Are there any ongoing costs after I buy?

There are no hidden costs. The price you see includes the stimulator, ear clip, conductive paste, charging cable, and everything you need to get started. Shipping is free to most regions.

The only ongoing cost is optional replacement consumables - ear clips and paste - which typically last several months and cost under $15 to replace. There are no subscriptions, app fees, or required add-ons.

Can I pay with HSA or FSA to save even more?

Yes. Our stimulators are eligible for purchase with HSA (Health Savings Account) and FSA (Flexible Spending Account) funds. This means you can use pre-tax money to cover the cost, making the effective price even lower than the sale price.

Simply use your HSA/FSA debit card at checkout. If your provider requires a letter of medical necessity, our support team can help with documentation.

Are sale items the same quality as full-price products?

Sale items are identical to full-price products. Same hardware, same firmware, same packaging, same accessories in the box. The only difference is the price.

Sale items also receive the same 2-year warranty and customer support as any full-price purchase, and a Vagal Buddy or Vagal Oh! bought on sale keeps the same 45-day money-back guarantee. We never sell refurbished or B-grade products.

What does the 2-year warranty cover?

All Vagal stimulators include a 2-year warranty covering manufacturing defects and hardware failures. If your device develops a fault during normal use within 2 years of purchase, we will repair or replace it free of charge.

This warranty covers the stimulator unit itself. Consumable accessories like ear clips and conductive paste are not covered as they are designed to be replaced periodically, but they are inexpensive and available in our accessories section.

What is your money-back guarantee?

Vagal Buddy and Vagal Oh! come with our 45-day money-back guarantee, with no questions asked. Not right for you, or not satisfied for any reason? Email us within 45 days of delivery and we will arrange a full refund of the stimulator.
