“2 hour auto off” I really hate that feature. I would be in for 11ty and give them as gifts if not for that annoyance.
You can thank the FDA and our overly litigious society for that. Auto-off is mandatory on most heating pads.
Well, that and the fact that prolonged exposure to heat can damage tissues, while (like a frog in a slowly warming pot) you don’t notice any significant discomfort.
