Felt daft ordering it
Felt a bit daft ordering it, if I'm honest. Put it on for the first time and my wife took a photo, which is fair enough. It works though.

Cold, dark and quiet, in an instant.
One piece, 360° gel cold and total blackout, pulled down over your eyes. Built for the bad days you can’t fight — only get through.

Twenty minutes of somewhere else. Cap down, curtains already shut, and the room stops shouting at you.
-
Two minutes in, it lets go. The pain drops to something you can ride out instead of losing the day to.
-
One piece, not a kit. 360° gel cold, total blackout and gentle pressure — nothing to clip on, nothing to lose.

Fits my actual head
Every other one I've had either wouldn't go over my hair or froze my ears off. This does neither.

I'm the worst person to sell to
Look, I'm the worst person to sell to. I've tried the magnesium, the daith piercing, two different mouthguards. This one stayed. I don't know why it works for me and not the others and I've stopped trying to work it out.

Honest four stars
Four stars because I wish it lasted longer. Everything else I like. I've since got a second and I've stopped noticing the problem, which probably tells you something.

The light stops screaming
Best way I can put it is the light stops shouting at me. Cap on, pulled right down, curtains already shut. Twenty minutes of being somewhere else.

The vice loosens
Two minutes and the cold gets through and that vice feeling starts to let go. It doesn't stop the pain, I'm not going to pretend it does. But it turns a nine into something I can lie down and get through.

Six of the 1,800+ — one for every question we get asked.
The Worst-Day Guarantee
60 days. Real bad days, not a quick try-on.
If it doesn’t make them more bearable, every penny back — and you keep the eye pillow, the pouch, the Ear Band and the Protocol.
Judge it on a real bad day
Sixty days is long enough for the rough ones to actually arrive. Keep it in the freezer, use it when one comes, and judge it on the worst of them — not on a curious ten minutes in a bright kitchen.
Every penny back — keep the extras
If it doesn’t make your worst days more bearable, tell us and we refund the lot. The eye pillow, the sealed pouch, the Ear Band and the Migraine Day Protocol stay with you. No labels to print, no questions that are really accusations.
Why we can promise this
Because almost nobody takes us up on it. No miracle claims — one small promise, made in the community’s own honest words: more bearable. That promise survives contact with the real days that actually count — the only test that matters.
The six above are why. See the kit.
