I am using a lavatube and an inferno, both of which seem to have the same issue. The lights work as expected on the lavatube. On the inferno, the light blinks when I try to activate it (I'm not sure if this is normal). Although the lights seem to work on both devices, neither get hot or produce vapor. After googling these symptoms, I believe that I may have over-tightened the tops, causing the center pins to stop making contact and completing the circuit. Therefore, I followed the instructions here (http://vapingguides.com/blog/vapor-trails-2/atomizer-and-cartomizer-connection-problems/), but to no avail. Please advise.
