Lots of good advice here. But yea a lot of ppl are saying the Uwell crown is great, the Pico looks like a cool kit, and that RBA from fastech is something I had no idea about. Is stuff from fasstech reliable? I don't wanna get something that's gonna blow up cuz it was machined crappy. Things seem to be working ok now. As if these coils need to be broken in or something...idk. I'm not sure if I'm ready to build my own yet. I'd have to learn more about it. I'm waiting to try the nickel and the Clapton coils I got. Wanna burn out the one I'm using first. Do ppl swap coils regularly or is leaving it laying around bad or something.
