How quickly does it work?
Most women feel their cramps ease within about 5 minutes. Wrap the heated belt around your waist, switch it on, and dial in the heat and massage that feel right.
Is it drug-free — and who shouldn't use it?
Completely drug-free — just soothing heat and gentle massage, no pills and no side effects. Heat and massage have been used to ease muscle cramps for generations. That said, check with your GP first if you're pregnant, have reduced skin sensitivity or circulation issues, or any condition affected by heat — and don't use it over broken or irritated skin.
Why not just take ibuprofen?
If painkillers sort your cramps, brilliant — keep doing what works. But painkillers travel through your whole system, take time to kick in, and only really work if you catch the cramp early. flutter works differently: soothing heat and gentle massage relax the cramping muscle at the source, in minutes, with nothing to swallow — and you can use it alongside painkillers on the worst days.
How long does a charge last?
A full USB-C charge gives you up to 6 hours of soothing heat and massage. Top it up between cycles — flutter is fully reusable, with nothing to replace or refill.
Is there a money-back guarantee?
Yes — 30 days, no quibble. If flutter isn't for you, send it back for a full refund.

my first properly pain-free period in years. i wrap it on, turn the heat up, and the cramp just melts away — i honestly don't know how i coped before.

i've retired my hot water bottle. drug-free, quiet, and it works within minutes — not an hour later like painkillers.
