Amazon.com: Sunbeam Heating Pad for Neck & Shoulder Pain …

I found no odor. I plugged it in, put it against my neck and shoulders and cranked it on high. After two hours there was a slight odor. I can’t explain it but it was not something that made me ill or caused me to throw it out in the yard and dial 911 to ask for a Hazmet Crew to rush to the scene. When it was turned off, there was nothing.
