These One devices are AMAZING. My anxiety dropped, good things started happening, this continued the domino effect of positive things happening in my life.
I had a necklace break and the customer service was excellent. Mary J went to the absolute ends of the earth to make me happy. Friendly, great people. I believe in them and I wish them all the best.

“ I’ve been using OneDevice for a while…
“ I’ve been using OneDevice for a while now and genuinely believe in it. What I like most is how simple it is. I can wear it throughout my day without having to think about it.
For me, the biggest thing I’ve noticed is an overall sense of feeling calmer, more balanced and more grounded. It’s quite subtle, but the longer I’ve worn it, the more I’ve become aware of the difference.
As a sports therapist, I see around 30–40 clients every week and I’m always interested in different ways we can support recovery, performance and overall wellbeing. I’ve shown OneDevice to many of my clients and there has been a lot of genuine interest in it.
I would never recommend something to my clients that I didn’t believe in or use myself, and OneDevice has become something I genuinely enjoy wearing and talking about.”

A Complete Nightmare: Fake Reviews, Zero Support, and Broken Promises
I bought TheOne Device because it promised to be a seamless, cross-platform solution. Instead, it has been an absolute nightmare to use, and trying to share my honest feedback has exposed just how shady this company really is.
• Shady Review Censorship: The most frustrating part? When I tried to publish my review on their official site, the system blocked it from posting. It is completely obvious now that the overwhelmingly positive ratings online are fake, curated reviews designed to trap unsuspecting buyers. They actively suppress negative feedback.
• Terrible Customer Service: When I reached out to resolve my issues, I was met with radio silence. Their support team is non-existent, leaving paying customers completely stranded.
• Useless "Interface" Design: The entire user interface is just a tiny, little colored light. It turns on—and that is about it. It is completely unclear how it is supposed to work, and the device seems permanently stuck in some locked-out mode that I cannot break. Because you offered zero help or information, I actually had to use another AI to help me figure it all out.
• Zero Usability Information: There is a total lack of easily found information on how to actually operate the device. No clear manuals, no helpful FAQs, and no onboarding. You are completely on your own to figure out a broken system.
Avoid this product at all costs. It is a waste of money backed by a dishonest company that silences its users.

I purchased this item to support with…
I purchased this item to support with C-Ptsd. I have found that I am less reactive when wearing it and I certainly feel more grounded.
I'd say shipping needs to be looked at as I had some difficulties collecting my item as 6 different courier services were used. The item itself is attractive to the eyes, it does sit a little heavy around the neck but not a problem.
Taking it on and off for showering/charging is a pain, might just be my dumpy fingers and thumbs but I do struggle with this. The chain also broke which I put down to donning and doffing so often, I was upset over this as I'd paid extra for the gold chain. Thankfully the chain broke whilst at home and I didn't lost the pendant, just a risk that needs looking at.

First of all I want to say this a truly…
First of all I want to say this a truly novel concept and OneDevice has executed it flawlessly.
I’ve had my device for about 6 months. In that time it very quickly became a daily staple. It is not an overt, light switch kind of thing but I CERTAINLY notice when I am not wearing it. From a general sense of calm to enhanced tolerance and patience in normally frustrating situations, this device helps. The ability to change and cycle between solfeggio frequencies is also incredible.
As medicine catches up to ancient wisdom traditions, this is an exemplary, convenient demonstration of the way frequency and vibration influence the body.
To the OneDevice Team, keep doing what you’re doing!

Hi Julie,
We are truly sorry that you are still waiting for your order, and we completely understand your frustration.
We want to be fully transparent about what happened. Over July and August, unforeseen delays in our fulfillment process set us back well beyond the timeline we had originally anticipated. We know how disappointing that is, particularly after being given an expected date more than once.
Fulfillment has now resumed, and the majority of preorders have shipped. The remaining orders, including customers who are still waiting, are being processed as a priority.
We tried to locate your order with the information available to us, but we were unable to find one under your name. So we can put this right quickly, please contact our support team with your order number or the email address used at checkout, and we will personally look into it and provide a clear update as soon as possible.
We appreciate you bringing this to our attention, and rest assured that we are committed to making this right.
Warmly,
The OneDevice Team

Device Evaluation
Hello,
I am glad to offer some insight into the One device and the effects I (and my mate) have perceived.
I've worn my medallion every day since I purchased it, and I've noticed a real, consistent shift in how I regulate my emotions. There have been moments when I've taken it off and felt anxiety start to creep in — then put it back on and, within minutes, felt myself settle into a calmer, more grounded place. It happens with almost no effort on my part. Even accounting for the possibility of placebo, that shift toward calm and resilience is something I've come to notice and rely on.
I liked it enough that I bought one for my partner, who deals with anxiety. He's told me it's helped him regulate his nervous system as well.
One piece of feedback: the device runs a little bulky. I understand the newer version is smaller, which is a great improvement. I'd also love to see customizable "toppers" available — different colors, crystal druzy additives, initials, or stones with different perceived energies — so people can make the piece feel more personal to them.
I intend to purchase 4-5 more for holiday gifts.
Respectfully,
Dr. Aleatha Pardi - DNP

This product actually works!!
After using the OneDevice for around 2.5 months, I feel a lot calmer, and my days feel lighter. This device definitely has made a positive effect on my mental health, my sleep, and even my relationships with people. I can't explain what it is, but it works. Also, I love the look of the device as a necklace. The product team has done an excellent job designing this so that it looks like a piece of jewellery that I would actually like to wear and show people. It's rare that I find a product that actually has helped me these days and the OneDevice is definitely something that I wear and use every single day and would recommend to all my friends!
