Query: Love Thermofore!

I was first introduced to the Thermofore heating pad 20 years ago. I have bought or encouraged others to purchase a Thermofore. My old one finally broke so I immediately replaced it. I love the way it heats up taking moisture from the air. It really helps my aching back! I even like the switch that you have to hold for the Thermofore to heat up so you control how hot it gets and for how long. Great product!!
