While tube mods are great. Starting with a tube mod can be a little overwhelming. In my honest opinion, I'd advice you try an ego twist 1000mah with a vivi nova. I used to smoke a pack a day and my twist can last me a day and a half on a good day(and a half). You can get a vivi nova from madvapes and a twist starter kit from Totally Wicked. Their twist is called the tornado twist but the device is a genuine ego twist.
I'm sure there will be many who disagree but that's my opinion.
Why do you say that using a tube mod could be a little overwhelming? I have actually seen others type that in reviews and did not know why.
