Hello guys, I've got a problem with my sigelei 30w. At the local shop I bought a kayfun had them set it up for me, when you fire the device the watts reading jumps around it'll go from 8w up to 10.5 and then settle on the watts i actually had it set for. I got some kangertech 1.2 coils for the protank it does the same thing. Then I but the nautilis on with 1.6 coils on and it's fine, WHAT THE HECK GUYS?!?!?
