Hi Dr Ija, Thank you so much for taking the time to share such an honest and detailed review. We're sorry your experience so far hasn’t matched the excitement and expectations you had going in. Sleep sensitivity in particular can vary from person to person. There could be a few simple adjustments we can suggest that might make a difference. We’ve had many customers who have seen remarkable improvements in their sleep quality and patterns, so it may simply be a matter of optimizing how and when you’re using it. We’d genuinely love the opportunity to support you and make this a better experience. If you’re open to it, we can set up a quick call to walk through how you’re using the device and fine tune things together. Please feel free to email us directly at [email protected], and we’ll arrange a time that works for you. Thank you again for giving it a fair try — if you end up not loving it, we’re happy to offer a full refund.

Hi Samuel, We completely understand wanting reassurance, especially with an investment like this. The device is designed to operate very subtly. It does not create a strong external vibration that you can feel on your skin, and the sound is extremely quiet, typically only audible if placed very close to your ear in a quiet room. If you still have any doubts about its functionality, we would be more than happy to look into your device to ensure everything is working exactly as it should. We can also connect on a call or communicate in whatever way feels most comfortable for you. Just email us at [email protected], and we’ll gladly arrange it. We truly stand behind our product and take great pride in our customer service. We will do everything we can to assist you in the best way possible.

Hi Dianne, we’re really sorry to hear you’re feeling disappointed. That’s absolutely not the experience we want you to have. First, regarding sound and vibration: the device is designed to operate very subtly. It does not produce a strong external vibration that you can feel on your skin. The sound is also extremely quiet and is typically only audible if placed very close to your ear in a quiet room. So not hearing or feeling much is completely normal. As for the red, yellow, and green dots, those are part of the visible light indicator and frequency cycling. Each color corresponds to one of the Solfeggio frequencies. The device cycles through them, or you can select a specific frequency mode depending on what you prefer. We’ve tried to locate your email in our system, but we’re not seeing any account that matches the name used here. Kindly double-check that your message was sent to [email protected] with your name so we can locate your account and assist you right away. And of course, if you’re not happy with the device, we’re more than happy to help you with a return and refund.

Hi Mohamed, thank you for sharing your experience. We completely understand how disappointing it can feel when results are not immediately noticeable, especially with a product where many people do feel something quickly. One important thing to clarify is that OneDevice is not designed to create a noticeable “feeling” for most users. Personally, I don't feel anything myself - but when I look at my sleep and HRV stats, the results are clear. The effects are typically regulatory and cumulative, similar to supplements, magnesium, or long-term sleep optimization, not acute or sensory. That said, every person’s nervous system, stress baseline, and health profile are different, and for some users it can take several weeks of consistent use to notice meaningful changes. This is why we offer a full 90-day money-back guarantee. We genuinely want you to have a positive experience. If the device isn’t meeting your expectations, we will gladly arrange a full refund for you (our customer care team already reached out to you via email). Thank you again for giving OneDevice a try. We appreciate you! With gratitude, Dmitri Co-Founder, The One Device
