It's from 2015 but this thread seemed like the perfect place to post this.

James Lauria was vaping with a mechanical mod when it exploded in his face, causing third degree burns and putting a dime-sized hole in the roof of his mouth.
The injuries were so serious that he had to be airlifted to the University of Alabama's burn unit, where he spent a week in the ICU. Six weeks after the injury occurred, he’s still unable to eat solid food and is currently on liquid diet. He’s going to be fitted for a prosthetic that will close up the hole in the roof of his mouth, but it still seems like he has a long way to go before he recovers.
FWIW, on a single battery mech I've never gone lower than 0.5Ω. IMO there is no need to. YMMV.
I don't give a rats azz what anyone says 0.15Ω, 0.2Ω on a mech is dumb and seriously asking for trouble.
If looking to blow gargantuan clouds buy yourself the proper regulated mod and be done with it.
