Hi all, i'm new to vaping, about 3 months now, anyway just got into rebuildable atomizers, i have an A7, igo-L, vision eternity and mini octopus or also known by the squid. Love the vision eternity comes with extra pre made wicks which are very easy to change you just gotta be careful when you change the wick they are pretty fragile inside to me anyway, but they hold a lot of juice and vape great, don't think i will try to make my own coils for this yet so i buy pre made ones there cheap enough to buy. On the squid i build my own coils, very easy for a 1st timer and the tanks work very good, you can also buy pre made wicks for this cheap as well if you shop around. On the A7 and igo-L, well i hated them and thought they sucked at first. I was building the coils good, after some practice as i wasted a lot of wick and wire in the process but still i hated them. watched a lot more vids on you tube on those two tanks and realized it was not the quality of the wicks i was building but rather my installation of them, needless to say now i have that down pretty good and i now like those tanks as well--So the moral of the story is, if your new to rebuildable's just be patient, you'll figure it out and all will be good. and any of the above tanks i mentioned are a good tanks to start with--Sorry this was so long
