The device is simply beautiful. I never wear necklaces but I am addicted to wearing this device. I have had it now for almost 3 weeks. I feel more calm for sure!! Highly recommend to everyone. I really liked the Gold Version as well, it was a hard decision!

Hi Lisa, we love that your OneDevice has become part of your daily routine and that you’re feeling calmer. The gold version is indeed beautiful! We can only imagine how tough that decision was. :)

I really don't know where to begin...this device has changed my life. I've been severely depressed and anxious for many years now and I've tried many different options, but none have made much of a dent.

After receiving my device, I put it on and wore it around for a few days. I then became disappointed that it didn't have any impact, but then, out of the blue, I started to "feel" it. Not in the physical sense, but really "feel"! I can't explain it, but it's been amazing.

I'm sure folks might say, "well how do you know it's that?" and that's a great question, but one I have an answer to. I know it works because this very morning was the first time I've taken if off in a while and as soon as it came off, I once again "felt" something, but this time it was the depression and anxiety coming back...and it stayed until I put it back on.

All I can say is this device has worked for me, changed my outlook on life, and made me feel more..."ME"! Thank you for making this device! <3

Hi Paul, thank you for sharing such a personal experience with us. We’re glad OneDevice has brought you a sense of comfort and helped you feel more like yourself. Sending you lots of care as you continue your wellness journey.

I understand that holding the unit horizontally and tapping it changes the color/frequency. That works—I can set it to light blue, but seconds later, it starts cycling through all the colors again. Is it supposed to maintain the color/frequency I select, or am I missing a step? Other than that, it been one week now since I started using it. Regardless of which frequency I am on, I’m starting to feel a shift physically, energetically, and oddly enough, a deeper connection to animals.

Hi Anthony, thanks so much for sharing your experience! We’re glad to hear you’re noticing a shift in how you feel. Our team reached out via email to help with your frequency settings and answer your questions. We'll ensure you have the best possible experience with OneDevice.

The effects are subtle. I'm usually a skeptic about these things but I feel different when I'm wearing it. I'm glad I bought this. Hopefully I can be more help on how it actually helps. ...not just a vague feeling I can't describe . I'm still wearing it daily . One thing is weird though. Maybe nothing buty dog is Soo much calmer around me. He never snuggles next to me but for some reason I'm his snuggle toy after eight years? Weird eh I will report back again after a while ..

Hi Paolo, thank you for this amazing feedback! We love that you’re keeping an open mind and paying attention to how you feel! And the unexpected extra cuddles from your pup are such a sweet bonus. We’d love to hear how things go as you continue wearing it. Keep us posted!

The device is working very well for me. Since using it, I’ve noticed an overall calmer sense of well-being. I feel more grounded. Certain situations in both my personal and professional life, which would have stressed me in the past, don’t seem to trigger me as much. Aside from sleep, showering, and exercise, I wear it all the time 😀

I'm almost scared to go with out it due to my disease, severe pain and complications. I used to cry everyday from having a hard time making it through everyday and since I wore the device I felt more stable and the crying went away.

Float Tank / Float Therapy Must Have
I became intrigued after hearing your appearance on Sean McCormick’s Optimal Performance podcast. When I later saw Sean wearing it, I reached out to ask how he liked it. His response was simple: “Get it.”
I’ve been using it for about a month now. The effect is subtle, but noticeable from the moment you put the necklace on. Wearing it feels very intentional—almost like part of a personal practice. If you’ve ever done a float (sensory deprivation), it gives me a similar post-float glow. Placing it on my bedpost at night also seems to support much better sleep for me.
After a few weeks, you start to notice the moments when it’s not on your body—almost like a reminder to wear it. Recently, I’ve noticed that the necklace holds the most value for me after meditation, and especially after a float session. Paired with that post-float glow is where I’ve felt the strongest effect (yes, I’m calling it that).
I’ve now worn it before and after two float therapy sessions. Last night, during a float, it felt like I unlocked something additional. I had a transformative vision in which it became clear that this necklace is a powerful tool. As I exited the float tank, I saw my necklace hanging from a coat hook. When I put it on, I felt a strong sense of energy and connection between my body and the device.

Thank you, The OneDevice team.

My order has arrived, and I am truly fascinated by the device. Within just five minutes of wearing it, I felt a deep sense of calm and balance come over me. It harmonized me instantly and gently brought me fully into the present moment.

I am already recommending the device to all members of my family, as the experience has been truly impressive. Thank you for the amazing work you are doing—please keep it up.
