5th post!!
Good luck bro. whatever you choose. I recently purchased a Provari it's a expensive mod but it's the best I have tried and I am sure the benefit of it will pay for itself in no time. VERY Convenient as well.
Welcome to the best damn e-ciggie forum on the planet, congrats on your fifth post, and congrats on buying what is arguably the finest all-around APV (that's ECF-speak for ".....in' mod") on the planet. I don't own one yet, but that injustice will be righted in good time. The V2 is my "stranded on a desert island" choice - if the island happens to have a 110 outlet, and a case of juice happens to wash up on shore. Unlikely, I know, but "Be Prepared" is still a great motto to live by.
Now you can use your ability to post anything, anywhere (well, except "Ask the Veterans") to sing the praises of variable voltage far and wide.
Speaking of that, a quick question: Would you have considered a Prodigy V3 instead of the ProVari V2? The Prodigy has two settings; 5 volts, and 3.7 volts IIRC. If not, why not?
I ask that because I've never understood why anyone would advise a beginner to start with a fixed-voltage device instead of a variable-voltage one, especially since the introduction of the Joyetech eGo-C Twist.
