I remember being a newbie.
I remember thinking how "fiddly" this electronic cig stuff was.....it was daunting, and I was using pretty simple stuff back then.
My advice for newbie stuff, unless you're a hobbyist, is get something simple and something that is not going to make you cough your brains out, etc. You can ALWAYS upgrade and the first thing you
buy can be relagated to backup.
therefore, I err on conservative side with newbies. I don't think they need to learn about temp control, single batts, chargers, and all that if they have NEVER picked up an ecig. Just the first few weeks of
vaping and finding
ejuice they like is going to be more than enough challenge.
A simple regulated PV with some safety controls is fine.
