ZQuiet, Anti-Snoring Mouthpiece, Comfort Size #1, Single Refill, Blue, Made in USA, BPA-Free, Medical-Grade Material

El producto venía abierto, desconozco si fue la aduana, pero dejo el comentario por si a alguien le sirve

$40+ for a piece of plastic that you're not even allowed to return if it doesn't work, AND they "advise" replacing it every 4 months... Wow, maybe I should consider entering this business.Almost every similar product barely manages to achieve more than 3 stars in reviews, and there's a good reason for that. It simply DOESN'T WORK for everyone. This alone should prompt the company to reconsider their return policy. There are numerous different reasons why someone snores, and adjusting your jaw forward is NOT a universal solution as the video suggest. I've been trying various solutions for my snoring, and so far, nothing has proven effective. This has been yet another discouraging attempt.It's exceptionally frustrating to discover that returns are not even an option, especially when there's a "return" button available. However, upon clicking it, you realize it cannot be done.The piece itself fits snugly between my teeth and doesn't cause discomfort to my gums, as some reviews suggest. However, apart from pushing my jaws forward (which is genuinely uncomfortable), it also keeps my mouth open. Perhaps with time, it might become less uncomfortable, but I'm not willing to give it that chance. I understand that it may take some time to get used to it. The instructions themselves advise patience. However, literally 30 seconds after lying down in bed, my throat relaxes, and I start snoring, EXACTLY as if I didn't have anything in my mouth, but now with the added discomfort of the piece. It's been a significant waste of time and money.

المنتج سميك جدا على الفم ولا تستطيع وضعة اكثر من دقيقه فمستحيل راح تنام فيه كذالك المنتج لايثبت و صعب تثبيته في الفم.

Gracias, es lo que esperaba me sirvió mucho.

It need to get used to it, but it works
