Non vérifié23 juil. 2026À proscrire absolument
Ma commande est arrivée bien après la date annoncée, incomplète et inutilisable puisque le mode d'emploi manquait. Le numéro de téléphone indiqué pour le contact n'existe pas. Ma demande de rétractation, pourtant formulée dans les délais légaux, n'a jamais été prise en compte.

Non vérifié19 juin 2026Device useless, refund policy worse
The device is a joke: it shocks you while you sleep but doesn't actually achieve anything. I used their money-back guarantee, returned the device at my own expense and received confirmation that it had arrived and that a credit had been applied to my account. The refund never showed up and I have been chasing them for months, always getting the same answer. The phone number doesn't work, nobody replies to emails, and my card issuer couldn't help either. Avoid them.

I ordered the sleep apnea device and it is useless. I had a sixty-day trial and sent it back. Two months later there is still no refund, and every time I email they say they are busy. Do not buy this.

Non vérifié13 juin 2026Z3 Pro not a good sleep apnea product
I could not wear the Z3 Pro for the full sixty-day trial. I emailed to explain that the device kept detaching from the patch under my chin, and after a little over three weeks it burned my chin and left a painful scab. I requested a refund in March, had to send several emails to satisfy their requirements and returned the device, but three months later I still have no refund and no reply. Their website now even blocks me with a message saying it is not available in my region, although it was when I bought the product. Horrible company.

Non vérifié3 juin 2026Return received, still no refund
I already reviewed this company about six weeks ago. I returned the product unopened and unused, and tracking shows their warehouse received it in mid-April. As of late May they still say the return is being processed. I never even used the product: my snoring was temporary, caused by being intubated for shoulder surgery, and had stopped before the device arrived. Stay away from this company.

Non vérifié31 mai 2026Shady refund practices
The product stopped working for me after a few days; I think my body simply got used to the electric impulse. My low rating is really about the return process, which feels deliberately difficult so that customers give up. I followed the instructions to the letter, waited more than thirty days and followed up. Support promised to get back to me and didn't. On my next follow-up I was told the warehouse had confirmed the return was in good order and that the credit would appear within three to ten business days. It never did. I was then told to wait another thirty days, and my questions about the date and amount of the refund went unanswered. I waited, filed a dispute with my card issuer on a Friday, and two days later suddenly received an email confirming the refund. The whole thing took four months. Don't give them the patience I did.

Non vérifié30 mai 2026Ten weeks and still no refund
I bought the Z3 Pro device and had a very negative experience. It did not work for me at all and I had panic attacks on both nights I used it, so I stopped. I then tried to use the sixty-day money-back guarantee: the return process was extremely long, complicated and time-consuming, but I followed every required step and sent the product back. The refund is the most frustrating part. I have followed up six separate times and received explanations and reassurances every time, but no money. Their policy allows up to thirty days, and it has now been roughly ten weeks since my return was processed. I cannot recommend this company.

Don't do it. Their website claims they have over four stars here, but if you look at this page you will see the reviews are terrible.

Non vérifié24 mai 2026Bad experience with the return
I returned my device unused and getting a refund has been an awful customer service experience. They advertise a sixty-day return if the device doesn't meet expectations, but the return process is tedious and cumbersome to say the least. They have had my device for almost three weeks and still cannot tell me if or when I will be refunded.

Non vérifié22 mai 2026Device doesn't work, refund never comes
The device doesn't work at all and there is no real customer service: replies take a long time and there is no phone number to call. I sent the product back and have now been waiting almost three months for my refund. It isn't cheap either. Don't buy it, you will be very disappointed.
