You know the drill.
Cramps hit. You boil the kettle, fill the bottle, hope you don't spill it — then you're stuck on the couch holding it in place with one hand. Or you're tethered to a wall outlet by a corded pad that still goes cold. There's a better way to stay warm. Emberly straps on for up to 6 hours of soothing, hands-free heat — from one quick charge.
