I'm a noob vapor and own 2 ecigs. I have the Volcano Magma (cigarette looking ecig), Volcano Inferno and I ordered and should receive a LavaTube this Tuesday. Now the reason for me owning 3 is simple. The Magma for when I leave the house and know I wont be gone for long. The Inferno will be what I take to work and the LavaTube is the VV unit I wanted for when I'm home chillin.. I see many of you own lots of pv's.. Many own multiple big battery units and I was wondering why? For the most part if you have a BB VV its going to hit the same as others so why buy so many.. I understand if you have a bunch of tanks filled with different juices but why one a Buzz Pro, LavaTube and a Provari or 3or4 types if the same Ego type setup?
