A small heated pad that straps around your middle and gets warm in seconds. No cord trailing to a wall socket. No hot water bottle sliding off your lap the moment you stand up. You wear it, and you carry on with your day. Heat is the thing most people already reach for when cramps start. This makes that heat portable, and adds a gentle vibration on top if you want it. What it does Warm in five seconds. Graphene heating technology, so it is up to temperature before you have finished strapping it on. Three heat settings: 50°C, 55°C and 60°C. A short press on the heat switch moves you up the ladder, or off. Four vibration modes, M1 to M4, on their own switch. Run them alongside the heat or leave them off entirely. 1800 mAh battery, about five hours to charge from flat. The input is 5V 1A. Charges over USB-C, so the cable already next to your bed will do. One comes in the box too. Switches itself off after 30 minutes if it stops detecting movement. Adjustable woven strap with a slider, worn over or under your clothes. Using it kindly Start on the lowest setting and work up whenever you want more. Do not use it while sleeping, do not use it over broken skin or anywhere that feels numb, and take it off when the warmth stops feeling good. The manufacturer states that the pad is not for use by people who are pregnant, people with cervical tumours, people with active gout, people with heart disease, or on unhealed skin wounds, and that it is not to be used while sleeping. Those are their instructions and we pass them on unchanged rather than softening them. Heat helps a lot of people with cramps. It is not a diagnosis and it is not a substitute for one. If pain is severe, or it is getting worse month on month, that is worth a real conversation with a doctor. We say that because we would say it to a friend, not because a lawyer told us to. In the box The pad, its strap, and the charging cable. If it is not right Send it back within 90 days and we will refund it. You do not have to explain yourself.
