RIZON Mouth Tape™

I've been a heavy sleeper my entire life and nothing has ever worked until the Onyx. It vibrates strong enough to wake me but silent enough that my partner keeps sleeping. Total game changer.

As a personal trainer I need to be up at 4:30am without disturbing my wife. The Onyx does it perfectly every single day. Battery lasts forever too.

Used to sleep through four alarms. My roommate had to physically shake me awake or I'd miss class. First morning with the Onyx I was up before it even finished its first pulse. Genuinely shocked.

Bought this for my husband who is the world's heaviest sleeper. After the first morning he was completely converted. We both sleep better now that I'm not woken up by his five backup alarms.

My husband is the lightest sleeper imaginable and I'm a heavy one. The Onyx solved our problem completely. He gets his rest and I actually wake up. We're both so much happier.

Five stars for the battery life alone. 14 days is not an exaggeration. I charge it twice a month and genuinely forget about it. The alarm has never once failed me.

Really good product. The vibration is strong enough to wake me which I wasn't expecting from something so slim. Knocking off one star because the buckle took some getting used to one-handed.

I have anxiety and loud alarms used to trigger a panic response every morning. Starting the day in a panic is horrible. The Onyx's gradual vibration changed my mornings entirely. I feel human again.

Two kids sharing a room, both light sleepers. My alarm used to wake them and the whole morning would derail. Now I wake up, they sleep in, and everyone starts the day calmly. Worth ten times the price.

Nutritionist with early client calls. The Onyx has become my professional standard. Clients respect punctuality and the Onyx ensures I'm never late regardless of what time the first call is.

Italian chef. My kitchen starts when the rest of the world is asleep. The Onyx handles 3am starts without disrupting my household and the physical wear of a kitchen job means I sleep deeply. It cuts through every time.

Film crew production assistant. 4am call times are standard. Hotel rooms with crew sleeping next door mean sound alarms aren't an option. The Onyx is standard kit for me now. Wouldn't arrive on set without it.

Retired military who runs a morning fitness group. I need to be up before my participants. The Onyx has ensured I've never been the last to arrive at my own session. The discipline it enables is exactly what I need.

Parkour athlete training early mornings before locations get busy. The Onyx gets me out for 5am sessions without waking anyone in my apartment. The physical training at that hour is incomparable to any other time.

I share a bed with my partner who has early shifts. Their phone alarm used to wake me every morning an hour before I needed to be up. The Onyx changed that. I sleep my full hours. That matters more than I can express.
