Im looking to get my first non-cigalike e-cig and i want vv and something that i can keep in my pocket at work and when im out of the house. I hear mostly good things about the protanks but heard they tend to leak. Is there a setup that is more durable for carrying in a pocket? I have a feeling I'm gonna need to get 2 setups, one for home and one for on the go. Any suggestions are appreciated.
