Most likely a mod with no vent holes since it blew all his teeth out .
Probably stacked batteries .
In anyways it's still a bad accident and I wish him a fast recovery.
Accidents happens and will happen but it's our responsibility as users to be as careful as possible . Know your device, know what battery to use , know about charging process .
Picking up any mod with some cheap or stacked batts is irresponsible. ( not saying that's the case with that guy but In general .)
