Review (3/5): Then I held it like normal and it was turning off
When I first tried this, I noticed that when I held the brush to my face, it was slowing down and then would stop. I would flicker the power button on and off thinking that was the issue, but then when I held the brush upside down, it worked without turning off. Then I held it like normal and it was turning off. I think there is an electrical issue with the brush...
