Questions about pain relief, fit, and safety
Clear answers to help you choose with confidence and comfort
How quickly does the heat help cramps?
Can I wear it under my clothes?
Yes. The slim pad and adjustable belt fit discreetly under most outfits so you can work, commute, or go out without drawing attention.
How long does the battery last on one charge?
A full charge provides 4-6 hours depending on heat level. USB charging is quick and convenient for on-the-go top-ups.
Is the heat safe for regular use?
The device uses medical-grade heating elements and an auto shut-off for safety. Use recommended settings and avoid extended direct skin contact without fabric barrier.
Will this help chronic conditions like endometriosis?
Many customers with endometriosis or PCOS report meaningful relief. Heat therapy improves blood flow and eases pelvic muscle tension as part of broader symptom management.
