i'm new to vaping as of 1/1/2013, but get obsessive with new habits. started with blus, then got an ego kit, then got clearos, then got spinners, then got an e-roll system, then got a vamo, then got carts and more clearos, then a v2 mod, then more batteries...you get the idea. not a huge fan of the vamo due to its size. the e-roll is my go to for work because i can stealth it easily, and swap carts without busting out needles or bottles of liquid. if i'm in the car, i prefer throwing a kanger t2 or a vision v3 on an ego batt. i've tried the t4, the evod, and the t3 bottom coil, but the t2/v3 have been the most consistent, idiot proof, and non-leaking attachments that also provide good vapor production. majority of my juices are either 80/20 or 50/50, and 16mg nic or higher.
not sure where i was going with that lengthy explanation except to reiterate that i use a cig-a-like daily, and prefer simple battery/tank combos to mechanical or VV/VW mods.
edit: would never use an e-roll as my go to device because of the lack of juice capacity, battery life, and heat issues during chain vaping
