Woah, lots of deleted messages on here. It's a shame, be kind guys. It's really not that hard, yeah.. he's doing something he shouldn't be because he hasn't the knowledge. Does he need a scolding though? You're not his mother, and a negative reply is only going to turn into more negativity and he's not going to want to learn because the community is being such crap to him. You can kindly tell him what he's doing wrong and express the importance of your words without being rude, it's quite easy.
I will though, +1 to all those here saying you should buy a regulated mod. Buy a regulated mod, get several months of experience with it, building coils on RBA's, and later on research thoroughly about mechs and then if comfortable, get back into it. But only when you are educated enough to know all of the variables and not only understand, but respect the responsibility which comes with using an unregulated mod which holds no safety features.
The vaping community does not need any more negative media attention, but most importantly and I can't express this enough, your safety is of the utmost importance. No one here however rude, wishes to see a person go through the pain of what a mech could do to you or others within your vicinity. Vape, but always vape safe.
