I started with a starter kit a month ago. My thoughts, which might not be worth much:
Get something that matches. 2.4 ohm
coils with a plain 3.7v battery will suck for the newbie.
Give them backups. Multiple
batteries and
coils.
An instructional sheet. If nothing else give them youtube links on how to use what you gave them on a sheet of paper.
Help them find the flavor/strength they need. Ok, good luck with this, but it's an idea?
Teach them to puff and not just lung hit an e-cig as apposed to a cancer stick.
