1) be aware of battery safety
2) realize what you are doing is potentially dangerous and could maim you for life
3) blowing the biggest cloud is akin to seeing "who's is bigger" and the only people that think it's cool are people who think it's cool, and that's usually young males. Girls.... well, man, girls couldn't care less.
4) is this what you want to get out of vaping? If so, more power to you.
5) he who blows the biggest cloud wins absolutely nothing except blowing the biggest cloud. Whoopty doo, you can blow huge clouds!
6) be prepared to spend major $$ on juice, because those "massive clouds" that "hit like a beast/freight train/sledgehammer" come at a cost. That cost is juice. But something leads me to believe you're not into this for saving money or to keep yourself from dying from tobacco.
Ah, youth.
