After a quick and not convincing passage on atomizers EC4 / EC 5 I went on this model. And this is the day and night! Beautiful finishes, 2 tanks supplied (Pyrex and steel if you are afraid of breaking the glass ...). I use resistors with a battery 1,5ohms iStick Elaef 20W for my setup in everyday use. Rendering of flavors and correct, it is possible to adjust the airflow for a draw more or less tight. Fast delivery and good packaging.
