Hey guys I'm new to building my own coils. Anyway. I built a dual wrap single coil reading at .6ohms. I did 8 wraps. They are taking for ever to heat up...I mean I have to wait 2 or 3 seconds of holding the button on my Manhattan mod before I can take a hit. And even then the vapor production is pretty low. I was hoping you guys could help me out..are my battery just crap? Or my coil build? I want to push some serious clouds. Thanks.
