I bought the Istick the store. Had I time to look at Amazon) have indeed paid 10euro more, but well worth it anyway. Fires good battery lasts in continuous use still long and looks great with the Aspire Nautilus Mini. Evaporated as hell and is the perfect combination against a Selbstwickler. Penultimate stage for battery carrier. For beginners is to enter the best battery of the full enjoyment of steam would have relatively little money. After that, only the selbstwickler there with battery carrier. Holts you ^^
