Vibration on the wrist wakes him where sound can’t. No app, no noise, no 6am fight.
Every alarm you’ve bought competes in the one channel his sleeping brain has already learned to shut out.
In deep sleep the brain stops handling sound the way it handles touch — which is why he sleeps through a phone screaming on the nightstand and still flinches when you put a hand on his shoulder. DawnBands skips the failing channel and vibrates against skin.
Alarms die because the brain learns to route them out. Vibration stays anomalous in a room it already ignores, so there’s nothing to tune out.
The morning it works, you don’t get a moment — you get an absence. No third trip up the stairs. No raised voice. No arguing with someone who genuinely does not remember turning it off.
You find out it worked because he’s already in the kitchen.
Wear it 60 nights. If he doesn’t wake up, you get every dollar back.
