Hi capt John
Heat lasts over an hour. I usually cover with light towel and/or clothing too make sure it isn't too warm, but the rice moves and fits to shoulders backs legs etc. as you move it pieces in the middle come out that are still warm. When the heat isn't as intense as u want it just pop it in the oven for 2 minutes and you are good to go.
My daughter gave me one at least 5 years ago and I was bumbled when I arrived and it wasn't here. Now I will have at least one here and up north. My shoulder and neck feel better already after carrying a 3 month old for the past couple days - thought I was in shape - guess not
