why it works when painkillers don't.
your nerves can only carry so much at once. flutter's gentle pulses keep the line busy, so the cramp's pain message can't get through to your brain — scientists call it 'gate control', and it's the same drug-free TENS technology midwives hand to women on labour wards every day. meanwhile, soothing heat relaxes the cramping muscle underneath and boosts blood flow at the source. two pathways, working at the same time, in one slim wearable.

my first properly pain-free period in years. i stick it on, dial it up, and the cramp just melts away — i honestly don't know how i coped before.
✓ verified buyer
i keep it in my bag now. 16 levels means i can turn it right up on the worst days and no one even notices it's on.
✓ verified buyer
i've retired my hot water bottle. drug-free, quiet, and it works within minutes — not an hour later like painkillers.
