Everyone who tries my mechs fires them weird the first few times. They hold it in one hand and fire with another finger. It still doesn't mean it was definitely the dual 18650 box version.
80% She's just an idiot who does not know how to properly use a mechanical mod. Mechanical mods if used properly are no more dangerous than a flashlight. I've done my research before venturing into my mechs. This... "person" clearly hasn't. It's just trying to sensationalise its mishap.
Judging from the report that the "Mouthpiece" blew out into her eye then I'd say it had to be a Hybrid mech mod - and most likely the battery vented due to shorting from the atomiser...
