Maybe a stupid comment, but I am a bit surprised that paper towel does not burn from the heat of the atomiser. In my 901 the cart sits right down into what looks like an element (new to ecigs, still working on the terminology). Anyway, I thought what happened was this "element" touches the wadding and atomises the nic/PG. I would have imagined that paper towel in proximity to this heat would at least run the danger of combusting or charring potentially contaminating the vapour.
Am I misunderstanding the mechanism?
