I don't get the whole sub tank craze from the consumer's stand point. They are all so similar and none of them can cast a shadow on a well built RDA for clouds or flavor. I guess they are just there for the beginner "Klowdz, bro" vapers who haven't learned how to build yet. And for the folks who want clouds but aren't inclined to build for themselves. I see the ease factor in a cloud maker with a prefab atomizer that you don't have to re-wet every few puffs, but I also see tons of posts from folks that are dissatisfied with the performance of their $40-$50 fad tank and the iffy reliability and short lifespan of a prefab coil. I like to blow clouds too, but my ADV is still a KFL. I can buy a new KF and a RDA (clones, of course) and a years worth of wire and wicks for the price of one of those tanks and a 5-pack of coils at the BM and have the best of both worlds with better performance and reliability.
