I said I was new to this obscure forum, not to vaping. I have only used authentic mods, never styled or replicas. I was asking if anyone has ever used a reputable clone. I understand the science behind them and built my own out of a few kits. Really not a lot to them. Really, if someone doesn't know how to build one, they shouldn't use them as they don't understand the composition of a circuit. I have 3f and fasttech sell them. Just was asking if anyone has used these before.
