okay, I haven't been doing this long, nor have I been cloud chasing for long. But let's have some common sense about something before we go judging someone.
As long as you know what voltage your battery is putting out and you are using only the safest of batteries(FRESH ONES AT THAT)
and what your resistance is and make sure there are no shorts the likelihood of loosing teeth, and or appendages is slim to none.
This isn't like handing a child dynamite? I have to ask...how much do you really know about battery chemistry and electricity outside of vaping? Like I said above...your chances of a quality fresh battery failing in this way without any shorts are slim! Even then you would suffer massive burns from the battery venting and the temperature of your mod heating up long before the battery in the video catastrophically failed.
Everyone was like "OMG YOUR GETTING AN RDA DONT LOSE YOUR FINGERS DONT LOOSE YOUR HAND BLAHBLAHBLAH" when I decided to get into rebuildables and cloud chasing. it just takes some common sense folks. Does it have it's dangers? Of course it does....anything dealing with a high drain battery pumping out 30+ amps on an extreme sub ohm build has it's dangers. However you can mitigate a lot of your chances of harm or loss of equipment with some common sense and battery safety.
