As others said - using a tank is essentially the same as dripping.
That aside, having to direct drip sort of defeats the purpose of the eRoll for me, which is a compact, portable device I can use when I am out, with as little hassle / maintenance as possible.
I would have to respectfuly disagree. I think using a tank vs. dripping couldn't possibly be even further away from each other.
When using a tank, you have to deal with
A. the juice type - and how easy it flows (vg or pg as an example)
B. Air bubbles
C. The size of the tank
D. Dirt or other objects blocking the feed hole in the tank
E. The Spike in the ATTY
F. The wick in the spike in the atty
G. The placement of the wick in the spike in the atty
H. The condition of the wick in the spike in the atty
VS. - Dripping
Drip a drop onto the coils and vape.
I'd say there is a vast difference
Not trying to argue, just trying to state my opinion.
Tanks and Dripping go together like a ...... in church.
