This was originally supposed to be electronic
This was clearly intended to be an electronic device initially. There is a power button on the front and when you pull off the back you can see where all the electronic components are supposed to be. I'm assuming that initially this was supposed to have a massage function, I honestly don't even know if it was originally supposed to be for the scalp. It's such a weird thing to see it being repurposed this way with zero acknowledgment of the lack of power. It feels cheap and weird.
