Anyone switching to e-cigarettes should rather rely on the same e-Cab from the same manufacturer, because the refillable liquid quantity in the e-roll simply too small. In addition, the batteries last only for the length of a normal cigarette, then they have to get right back into the cargo box. Good is the steam volume, as long there is enough liquid in the tank, I had also ordered the same to me a Eroll atomizer body. So I have two fully operational e-Rolls. Witzig is the charging unit, which looks like a mini-iPhone. Would it still have room for the 2nd cigarette, it'd give me 5 stars.
