Maybe I’m not your target market. I am not feeling calm. When I wear it, during the day I feel a motor running.

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.

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

Ordered and paid in full in early July (#10958). The delay was attributed to customs on their incoming stock. On 13 August I was told in writing that stock would be available 31 August, orders would be released for shipment, and tracking would follow. As of 31 August there is no device and no tracking. On the same day, the company is running ads announcing a new pre-order batch shipping 14 September. Scam!!!
Response from OneDeviceAug 31, 2026
Hi Kyle, We’re truly sorry this has taken longer than expected. We know waiting is never ideal, and we’re doing our best to fulfill all preorders as quickly as possible. Upon checking, your order is already awaiting courier pickup and will be in transit shortly. We’ve also sent the tracking details to your email today. In case you did not receive the email update, please check your inbox, including your spam or junk folder. The September 14 dispatch date mentioned in our current advertising applies only to new preorders placed now and does not affect your order. We truly appreciate your patience and understanding. We look forward to getting your OneDevice to you. Stay tuned, The OneDevice Team

I am seriously alarmed by this business. They do not respond to emails. They do not send out shipping updates when they push back drop dates. The place for "orders and support" linked on the email that bounces back when you send them inquiries isn't actually a link it's just a button that looks like a link. Even if the device was good, getting it and dealing with this company is not worth it. I've gone over a month without communication about a object I've purchased that was supposed to drop ship in less than 15 days from my date of purchase. I'm going on 2 months. I feel my only recourse is my credit card company at this point.

Hi Mary, Thank you for taking the time to share your experience — and we're sorry it fell short of what you expected. Looking into your case, we found that your email was sent to one of our no-reply addresses, which unfortunately isn't monitored for replies. It sends back an automated note with instructions to reach our support team through our contact form. We're already reviewing how to make that path clearer, so no one else runs into the same wall. On your order: we took extra time to complete quality assurance on the latest version of the device before releasing this production run; we'd rather be a little late than ship something that isn't right. The dispatch dates we share are also estimates and can shift slightly when additional testing is needed to meet our standards. We'd also like to clarify that the August 10 dispatch applies to new preorders only. Your order isn't part of that batch and is currently expected to dispatch early next week. That said, we completely understand if you'd rather not keep waiting. If you'd prefer a refund, we're more than happy to arrange it. Our team will be reaching out shortly so you can choose whichever option works best for you. Thank you again for your feedback. We take every customer concern seriously and use it to continually improve both our products and our service.

Scamming crap. I ordered my necklace June 23rd. Received it. Only worked a few hours and no longer worked. All in the same day. I returned my necklace with letting customer service know and they received it july 6th. Im still as of current out money for a product I do not have. This is ridiculous. Do not buy or waste your money. I will be filing a dispute for the charges and making sure all social media platforms are aware for future people so they know not to fall for this crap like I did. Update: as of current, 7/16/26, they have not responded to my case I opened with PayPal. PayPal communications online with customer service has confirmed this. Update #2: as of 7/22/2026, the refund was sent back to me. *please do your research on this product. While medical treatise out there notes frequencies can help, for such a small device for the price, it only worked literally a few hours for me then stopped. My overall opinion is that more improvements need to be made on this product to ensure proper overall working capability long term. If it did, I would have kept it instead of dealing with this headache for the return.
Response from OneDeviceJul 14, 2026
Hi Katie, thank you for taking the time to share your feedback. We sincerely apologize that your experience with both the product and our return process did not meet your expectations. After reviewing your account, we confirmed that your returned device was delivered to our facility on July 6. Once a return is received, it typically requires a few business days for our team to inspect and process it. Before the return was fully processed, we also received a chargeback request from your payment provider. To help resolve the matter as quickly as possible, we accepted the chargeback on July 10, allowing your bank or card issuer to begin processing your refund. At this stage, the refund is being handled by your bank. While refunds are typically credited within 5 to 10 business days, processing times vary depending on the bank or card issuer. If you have not yet received the funds after that timeframe, we recommend contacting your bank directly, as they will be able to provide the most accurate update on the status of the refund. We truly regret the inconvenience this experience has caused and appreciate your patience throughout the process. If you have any questions or need further assistance, please don't hesitate to reach out to us directly. We're always happy to help. Update | July 22, 2026 Hi Katie, Thank you for updating your review. We're glad to hear your refund has now been received. Throughout the process, our team stayed in touch with you to explain how the PayPal chargeback process works and to provide updates from our end. While we accepted the chargeback promptly, there can be additional processing time before the refund is reflected in your account, as the final timeline depends on PayPal's review and processing procedures. We're also sorry the device didn't perform as expected for you. While individual experiences and results can vary, we understand your disappointment and appreciate you giving our product a try. Thank you again for your patience throughout this process. We wish you all the best moving forward.

I ordered the 24K Gold One Device but received the standard black version instead — despite there being around a £100 price difference. On top of that, I was charged £71.27 in UK taxes and duties based on the higher-value gold product, which makes this mistake even more frustrating. This is such a basic fulfilment error that it’s hard to understand how it could happen in the first place. Even if the device itself works, the overall experience has been so poor that I no longer want it — I simply want to return it for a full refund. I contacted the company on 18 June 2026 with full details and photos. I only received an automated response stating a 24–48 hour turnaround. I followed their instructions and resent the email marked “URGENT”, but still no reply at all. The lack of any real customer service is unacceptable, especially when the issue is clearly their mistake. From what I can see, the only time One Device seem to respond to customers is when reviews are posted on Trustpilot — which says a lot in itself. Unfortunately, this has been an extremely disappointing experience, and I would strongly caution others before purchasing.

Hi Philip, thank you for bringing this to our attention, and please accept our sincere apologies for the experience you had. Receiving the incorrect item is not the standard we hold ourselves to. We've carefully reviewed your case and have already escalated the fulfillment error internally to understand how it occurred and ensure additional safeguards are in place to prevent similar issues in the future. We also recognize the frustration caused by the delay in communication. Over the past several days, we've experienced a higher-than-normal volume of inquiries, which has impacted our response times. While this provides context, it does not change the fact that you deserved a more timely response, particularly given the nature of the issue. Our team has already gotten in touch, and rest assured that we are working toward the best resolution to ensure this matter is resolved fairly and promptly. We take feedback like yours seriously and are committed to learning from it. We look forward to resolving this with you. 🙏

Device would not switch on - no response from the returns process in a week. Don't waste your money. No idea if the product would work if it actually switched on but no customer service whatsoever.
Response from OneDeviceJun 22, 2026
Hi Ben, we're very sorry to hear about your experience. Our team typically responds within 24–48 hours, so we'd like to make sure we haven't missed any of your messages. We've sent a request for additional information so we can look into this further. We stand behind the quality of our products and would be happy to help troubleshoot the issue. If the device is found to be defective, we'll gladly assist with a replacement under warranty or explore other appropriate solutions depending on your preference. We appreciate you bringing this to our attention and hope to have the opportunity to make this right.
