I had bought the RBA edition of the cloud beast king, I just checked the resistance of the coils, .40 ohms. It has SS Clapton coils, In temp mode it's at 360 F and works well. In wattage mode I get plenty of flavor and vape at 35 w, 45 watts is strong for me, 55 w is to much for me. It's good without a doubt but really over kill and I prefer the TFV8 RBAs. I have the air flow at about 1/4 of the way open for a little draw. I put it aside for emergencies.
