overall this product is great! warms up quickly and helps soothe cramps. it has three different temp and you can adjust different vibration modes. you can adjust the size for the waist as well. comes with a charger too! i recommend putting a shirt between the skin and the pad so it’s not super hot.
Works very well. I like that it inflates enough for me to feel it and it alternates between two chambers. You can also adjust the temperature and the tightness. I wish I had ordered this 8 months ago. I'm happy my purchase.
