I never did the Elf on the Shelf with my kids.
Although, ironically, I do have a little elf that sits on a shelf that my mom gave me from my childhood. He's pretty cute. For as ancient as he is.
Usually, asking my kids if they wanted to end up on the "naughty" list was enough to get them to simmer down. Kids can get so revved up this time of year. I have a friend who has implemented the same thing with her very young children and NO....they don't want to be on the naughty list.
I never heard of Elf on a Shelf except for on this forum.
Not saying it's good or bad, fun or not, but I'm older and generations of kids that I know wouldn't know what it is either.
Just my opinion.
