Amazing.
My cramps are so bad they make me pass out and for years I was on BC, which helped some, but I decided to get an IUD and let me tell you I thought I was dying. I couldn’t move, I couldn’t get out of bed, I felt like throwing up constantly. I decided to give these a shot and also got a pain medication, but these are amazing. They stayed warm forever and really helped. I used them on my front and my back — you really can use them anywhere — and they stick to you very well. I also have super sensitive skin and react badly to adhesives and these did not bother me at all.
