General:
Thanks for this super helpful comment! I had no idea that those pens required proper grounding, but I suppose that makes sense.
From my understanding, you'd need a multimeter to check the grounding. While the pens might be handy, unless you've previously confirmed the grounding, they don't seem especially useful.
Yeah... who woulda thunk it, not building things to code causes problems down the line? Not my in-laws that's for sure!
