I've been looking for an easy way to fill my cartomizers. I have heard about the condom cartomizer refill method where you just drip into the condom cap and press the carto down onto there. I have seen videos of this done with both the mouth end and the battery/threaded end. I have also heard small grumbles that this is either bad for the atty, or could potentially ruin the battery. Any thoughts on if its safe or not? I have a manual PigCig from LeCig if it makes a difference.
