There's no such thing as a "safe" gun....automatic weapons kill far fewer people in america than handguns....one of the things Mooch pointed out is... that if you have a regulated box mod with multiple batteries, and there are tears on the batteries, and they touch..it doesn't matter how many built in safteys you got on the mod you are going to wind up with a thermal runaway....when we tell people there are such things as "safe" mods and "dangerous" mods we are telling them if they buy a "safe" mod they can now be mindless and thoughtless...the dangerous part of the set up is the battery...and as long as you are carrying a battery around you need to pay attention. so if you are going to vape at all you need to be aware of the potential dangers, you can't ignore them because some salesman showed you how to press a bunch of buttons and told you your mod is "safe"..
