i started with those ego-C, there are not dripping atomizers, but they have like a small tank, very small.
i rapidly bought other stuffs, because after a few weeks, u replace the atomizer with a new one, then u rapidly need to buy new ones.
so i thought lets try something else, and i didnt regret buying other stuffs.
what is good in this pack ( if this is real joyetech and no copy ) is the charger and batteries. that u can keep for long time.
but the atomizers, well i wouldnt use em anymore, while i would still use a vivi nova or ce4 anytime.
+ they are a bit of a pain to refill, the plastic is hard and u can easily screw it. and if u replace that top plastic cap with latex ones, the taste get really nasty. thats what happend to me and thats why i moved to other and better system.
