In their words
- 5 out of 5 starsPairing the heat with the vibration is what made the difference between enduring the night and sleeping through it. I thought heat alone would do what it's always done for me — barely touch the pain.Fiona N.
- 5 out of 5 starsI just fall asleep now and don't wake up in pain needing to reset anything. I expected the auto shut-off to be annoying, like I'd have to keep turning it back on.Holly C.
- 5 out of 5 starsThis is honestly the first period product that's let me get through the day without feeling like I have to just push through the pain.Maria D.

- 4 out of 5 starsIt's the only thing that's kept up with how bad my cramps get. I assumed it'd be another product that looks good in the ad and does nothing once you're actually curled up in pain.Jenny M.
- 5 out of 5 starsI used to lie awake in pain most nights during my period. Now I put this on, and the auto shut-off means I don't even have to think about it — I just fall asleep.Sasha K.
