Then you must not be observing the same e-cig market as i am.
Yeah, phooey on the market, it's a fad being catered to, that's all. I remember when all the makers of sun glasses all thought we each looked our very best in alien sunglasses and you could not get any other kind. That fad passed, thank God.
For my part I just don't like boxes, and I don't want electronics in my vape and I know I'm not alone in that. I get the vape I want through they way I build my atty. To me it looks like the TC boxes are for those who, for reasons of laziness, inability, or limited native intelligence, cannot build an atty right.
