I am not at all satisfied with the product. maybe that's what I was not smart for "experienced" steamship, but from the manual, and I did quite a lot of technical equipment at the hut. A friend then helped me, because I already thought it is up to me. have also looked at dozens of videos (which is useless manual) and everything is done correctly. but: both e-zigis have getropf, ends at both, exactly as much as came in, also came back raus..besonders the mouthpiece wonderful. the battery lasts also only very short and if I want to charge, he is an evergreen, although the cigarette already blinks yellow or red. after hours append bleibts also just that.
