Very satisfied
I'm so glad I finally found a heating patch to relieve my menstrual cramps. I have never been satisfied by any heating patches sold in US, so I've always had to purchase heating patch from Korea or Japan.  I've used Thermacare in the past, which was always too hot and too big/heavy to wear for more than 3-4 hours. I am surprised by how comfortable and convenient this product is. Based on my experience, the patch also lasted more than 7 hours, which was longer than it's advertised.
