I gave them to family members and made a copy of the warning that is on the Warm Tater batting. I also gave them explicit instructions to only use them to warm food, not to leave the micro unattended and to wash before using if something spills on it. I also warned them that some people have had fires with them but I've used mine everyday for several months and haven't had any problem. I was going to make them to sell, but decided I didn't want the liability.
