So I have had an ecig before, but never really got into it. I ran across a really good deal on a Provari Mini with a J-tank about 2 days ago and Im hooked! One problem is that I try to find tutorials on how to properly utilize a variable voltage battery, best way to re-fill my J tank, and stuff like that. But all the tutorials I can find are extremely beginner practices. Do you guys have any suggestions? I just got a new toy, and I want to get the most out of it!
