“I was a little disappointed in the fact that it had to be plugged in to use. But I realized I could use a battery and it was still better than a standard plugin heating pad. It fits nicely and warms quickly. Also the 30 minute hut off is a nice feature. The cord is long enough to plug it into a battery and keep it out of your way. It has a pouch for a cooling pack if you wanted to use it that way. I recommend this item.”
