So my sister wants to get into vaping and I wanted to get her a mod as a gift. It's between a istick or Kbox cause I'm cheap as ...., and they're both pretty decent mods. I was wondering which one would you guys recommend? I know the Kbox doesn't go below .5 ohms but I doubt she'd subohm cause I was going to get a Kanger Subtank Mini to throw on the mod.
