I immensely enjoy the hobby/tinkering/nerdy aspect of vaping, in addition to the nic-delivery of course, and that's why I love mechs/rebuilding/DIY etc and learning as much as I can during... If you're not interessted in that(mechs), then just stick to regulateds, they're safe even without much precautions and fine solutions..
If you wanna use mechs, then read, read and read some more, and ask about everything you're in doubt about, especially safety...
You don't need to be a nerd about it if you don't want to, but atleast get ohms law calculation/calculators down and not building over CDR of battery. Also. don't use pinless-510 mods/topcaps unless getting the precautions down there first also...
