Ten years ago, I was given a smaller version of this heating pad and my puppy chewed through the cord and I thought I could never replace it! Finding the same heating pad with the convienent removable flannel cover was a nice surprise. I wasted no time ordering it and then ordered one for my nieghbor who was visting and saw mine. She wanted one too! The length of the heating pad gives me relief from the end of my spine to my shoulders and neck. I use it almost every day for a past injury. I also use it to warm up my muscles and relax on a cool night. I love this heating pad and the price is very affordable, worth every penny if you have aches and pains!
