Good to hear. First fill of a cartos is very important and determines the longevity of a carto. They have to be completely saturated otherwise poor vape and worse yet the element may burn out or the filler gets burnt taste which is impossible to remove. When I cleaned cartos ( no longer do) I occasionally used a hat pin to clear out the airway VERY slowly and carefully from the battery end of the carto- even after washing it was amazing the gunk that came out.
I will check that out. I tried one I did last night and still nothing. Poured more liquid into it until it was drenched. Hard to draw. Blew out the excess and wonder of wonders now it's working. Thanks for all your help everyone.
