I find the new coils different from the old. (Vertical new vs Horizontal old)
This isn't causing me problem other than having to run it a good few watts higher.
What power? What juice (PG/VG) anything unusual (high ohm readings etc?)
I had one which refused to wick, period. I can find no explanation, other than somebody had packed it to death with something and it simply didn't soak up the juice. I knew immediately, as the liquid just sat on the holes like the cotton had been sprayed with something liquid-proof. Very strange indeed. #2 'bad' Kanger coil in 3+ years.
