Self-diagnosed deepest sleeper alive. ONYX wakes me up in under 30 seconds. I don't know how, but it works.

My husband works nights. I had given up on quiet mornings. This thing changed our marriage, no exaggeration.

I've overslept job interviews, flights, and my own birthday party. Three weeks with ONYX and I haven't missed a single alarm.

My roommate used to throw shoes at me to wake me up. I haven't missed a single class this semester.

I use four alarms across rotations. Battery still lasts almost two weeks. The vibration is impossible to sleep through.

Got this for my boyfriend who has the loudest alarm in existence. Now he says it's the best gift he's ever received.

I take a 20-minute power nap every afternoon. The vibration wake-up is so much gentler than a phone alarm.

Strong vibration, easy setup, and works great without disturbing anyone else. Small, reliable, and perfect for hotels and flights.
