You can actually buy a small machine that does the NR R NR thing for you, you just line up the wires for the machine and it creates the connection. I'm guessing its around or under 50 bucks USD, though I'm not sure if it's still kicking around these days. With the increasing popularity of the Kayfun styled atomizers and the Aquas and Odysseuses and whatever other annoyingly complicated attys are out there, it'd probably receive good demand these days. Penelope clones anyone? I bet they're selling well if they're out there.
Anyone here ever used the AIOS or it's Ehpro clone? I was thinking about picking one up for my STNatty if it's easy enough the rebuild... I hear it has the juice hold capacity of a tank. But I don't understand the concept of it. How does it feel juice to the coil, anyone know or have a post reference where it's discussed already? It'd be a HUGE thing for me if it works well, I'd have a whole new favorite setup I bet.
