We don’t make claims. We follow the data.

Customers reported something
we never designed for.

People started calling about our VaguVibe describing an effect I hadn’t planned for and couldn’t explain. My honest answer? We didn’t run a clinical trial. So instead of making a claim, we shared the data with one of our doctors in New Zealand — and he’s starting a proper observational study. That’s how we do things here.

For the record
We follow the data.

These are anecdotal customer reports — not clinical claims. An independent observational study of VaguVibe is now underway. We’ll share what it finds, whatever it finds.

Why we’re telling you this

The easy move would’ve been to stay quiet.

When customers report an unexpected effect, a lot of companies either bury it or turn it into a marketing claim. We did neither. We don’t have a completed study, so we won’t pretend we do. What we have is honest anecdotal feedback and a real study getting underway to look at it properly. If you want a company that tells you what it knows and what it doesn’t — that’s us.

From the founder

Why this matters to me.

I spent my career as an engineer — you don’t get to claim a result you haven’t measured. That discipline is the whole company. Resona builds drug-free wellness devices, and when something surprising shows up in the field, we treat it like engineers: document it, hand it to people more qualified than us, and let the study speak.

— Mark Fox, Founder, Resona Health
