I've got the 1.2 in there..I don't know if I want to put another $12 getting 0.5 ohm coils to give it a another try *lol* (it came with another but Ed's got it or it's in the box..or heck if I know where it is) I just can't get any vapor from it..so giving up on it. I've got others that work so much better..so Im tired of mucking about with it.
I tried it again just now ..after that CRACK thanks I'm awake with very little coffee now *lol*
Have you tried the RBA deck? To me, the factory OCC coils heads will suffice in a tight, but the RBA deck rocks... and it comes with a coil already installed. Just add some cotton, prime, assemble, and you're ready to roll. It's also very forgiving... I've wicked it tight, loose, long tails, short tails, and used several different ratios of PG/VG from 70/30 to 30/70... no problems.
Been using an OCC coil for the last few days and you're right, they crackle and pop a lot. Just re-wicked the RBA deck and installed it (still using the factory coil it came with after ~6 weeks)...
much better vapor and no POPS!
p.s. If'n ya decide to ditch it anyway, PM me...
