On the right steamer

First thing first: you can two complete E-Rolls Assemble (unlike the 2-star rating written, possibly may be off, that what has changed in the scope of supply) of the supplied parts.
There is an almost complete e-roll available (missing only the evaporator), and parts thereof: another body, still 2 tanks, even a battery, a total of 2 welded evaporator. Once you have assembled everything goes, you get 2 E Rolls and an extra tank. For this purpose a charging case, which unfortunately can only accommodate an e-roll, but that's enough basically also.

The refilling of the tank is simple, you put the bottle tip into the liquid sufficiently large hole on top of the tank and pushes out a few drops. More also does not fit purely. It is important the tank not completely fill up, otherwise liquid can escape.
Easier and better to blow the refilling is via syringe with attachment (I use teat cannulas, no needles). In order to get deeper into the tank, but miscalculated one can easily times in volume and must press down the plunger with appropriate care. I use the syringe only to clean the tanks.

The tanks are made of two parts, like a tank-in-tank system. The small inner tank is filled with liquid, the outer space remains empty and the whole serves as mouthpiece. By the outer space, the air is sucked and it can be both cause drops outdoor "tank" form as well get in there Liquid. Both can then only by pressure rinsing (eg with syringe plus essay) are removed, namely by both injected water into the tank hole and the air hole on the other side. Whether the accumulation of fluid can be avoided in the outer tank, if one less turn draws, I do not know because I do not use the E-rolling itself. But it is certainly an advantage if you do not fill the inner tank to the brim.

The shop is very easy. In ordinary use, the charger goes all day and then takes several hours to the socket until it is full again. The E-Rolls must be charged several times a day, but since you as I said two pieces in this set receive and one of them always load in the cargo box can (once charged, is used as a mobile battery), no problems arise here.

The tanks hold depending on steam habit quite two-three hours or more (or even less), as well as topping up can be done in a few seconds on the go easy. It requires a Liquid bottle with tip, or alternatively you can also bring the reserve tank. These are supplied with lid and should not leak (again: not even tested because so far not needed).

One could of course buy models with a larger tank, but this fall on a lot more and are then no longer as a Pyro manageable (fag in mouth). So this is a matter of taste.

You get here a really small, thin model with the corresponding advantages and disadvantages.

Compared to Neocig (as a test model for disposal initially ordered) the E-Roll is again significantly smaller.

Disadvantages:

The body is secured by rotation lock on the battery, a minimum counter-clockwise rotation is enough to loosen the connection. This can also happen during normal handling easily, for example when changing tank. Is a bit annoying, but not dramatically.

It often form at very viscous liquids (VG!) Bubbles on top of the tank, which then runs after no more liquid in the evaporator. By knocking can try to move these bubbles you, but first you have to know (or remember) that one is there, and not the tank is empty. Also topping up is not possible with the short spikes of Liquid bottle when a bubble sitting on the tank hole. Best eliminated you this by rinsing the tank. Otherwise, the finger on the vial is pressed sore, and when pulling out one then the Liquid suppt on the finger. This is the only truly annoying to this model (although have no comparison to other models!). For a star deduction.

For starters, a really convincing model, certainly, there are still opportunities for improvement, however, is questionable to what extent these have an effect on the characteristics of this model eventually make (especially size and style). Since then you have to decide what is a important. And this decision is a newcomer certainly turn out differently than a E-cigarette veterans.
