I once turned a DE Hook off at a party, there was a little bit of a smoke smell , the guy turned it back on said he diddnt smell it.
He acted grumpy an like i was trying to be a wiseguy or something.
Few minutes later someone reported smoke comming under the glass at the left bottom
Kickback coil fried and board dammage.

I would always be greatfull if you turn my stuff of to protect it!
And i wil always turn off a pin in need of my help
