...but anything can go wrong. Rebuildable coils aren't the only ones that can be wonky; bought coils, or coils you just replace as in Protanks can be off, as well. A regulated mod can catch on fire, but then so can egos, with their subpar chargers, and so can our beloved cellphones, laptops, and tablets. Planes crash and drivers text on the roads. You literally can't hand a plate of food to a friend with 100% certainty that they'll survive the experience; they might choke.
My main worry about introducing a new vaper to a rebuildable even with pre-made, good coils is that they might think it's too much of a hassle. You stick the ends through the posts and tighten the screws, making sure it's the right distance from the walls and the posts, and positioned right. You measure resistance, clip the ends, test fire, reposition again, maybe tweeze a bit to take care of hot legs, uneven firing, then insert wick, then wet the wick. It's not a lot of work, but it's a bit more work than just screwing in a new head.
not fighting that argument either.
but the simple fact is - you have to LEARN - and you point out howmuch you yourself have learned - which is good, YOU know how to do it.
alot of new vapors are trying to skip everything learning wise, and "just get to the damn clouds already" - which is where some of these accidents/headlines are coming from.
taking the time to understand what your doing, helps alot and can help avoid these "accidents" 99% of the time.
