Query: Baby, it's cold on there

After using this thing for more than an hour, I still couldn't tell if my body was warming the heating pad or if the heating pad was warming my body. I tossed it under the bed in disgust and haven't used it since. It's got the fancy-smancy controls and velcro and looks pretty and shiny, but it's a major disappointment.Remembering Mom's old heating pad, I went online and bought a USED heating pad - that dates back to the 1960s. When it arrived, I was pleased as punch. Fire that thing up and put it on LOW and the radiating warmth sends you to a state of raptured bliss. Set it on high and you'll be able to drop a couple eggs on it and fry 'em up real nice.But this Sunbeam Heating Pad (featured here) is a waste of money. I was profoundly disappointed in its performance. On its highest heat setting, the warmth really is barely discernible. If you're in pain, you don't have time to waste on this.
