Yeah, and the real kicker is the damage might not even kill the part. It can just make it run worse or less stable over time. So you're chasing down weird crashes or bad performance, and the whole time it's because of a tiny shock you gave it months ago. That's what makes @jordangibson's point so solid. If you skip the strap, you might never know what you actually did. You just end up with a computer that feels a little off for no clear reason.

Check the heater's wattage before plugging it in.

My buddy's cheap heater actually melted his outlet last winter lol
