Spider Head Massager- I Got One For My Birthday

I did some Googling and there are apparently a lot of positive benefits of such a device. A nice head massage is always enjoyable, but I didn't feel anything from this thing. Maybe I haven't given it enough of a chance, so I'll try it out for a few days. Hopefully it will change my life.
Gear: Sony ZV-1, Apple iPad Pro, LumaFusion
