I have no wish to open up a vape shop in my apartment, so I only spend money to find what I like and then I'm done.
Had to do a bit of experimenting to find my current ADV, but I think I'm there.
2 Itaste VV3's and 3 Mini Protank II's in rotation. Simple, functional, portable, affordable.
The relatively short life of the 800mAh of the battery is offset by the fact that it is a USB passthrough, so I can plug in at my desk and vape while charging. And if I'm away from a Car charger or phone charger for longer, I always have a fully charged Itaste with me.
I have three Evod's and 2 Mini Protank 1's and two fixed voltage 650mAh Ego-T's that are currently "on the bench". Seriously thinking about giving away the Ego-T's and Evod's to a new vaper and prospective new vaper.
