yeah I am noticing the power on this thing is freaking crazy if I had this dual coil set up on my Primo 2.0 at 25w it would be like nothing next to no cloud but I am pulling a nice big strong cloud and good flavor with 25w and all I can think is WTF I have dropped down to 20w and starting to see a drop off and temp is still spiking to 415 for about half a second from time to time so maybe I am just seeing what the joyetech did not show maybe their firmware is not senative enugh to show the half second jumps?
