Refilling cartos is a hassle, though I intend to get an Ego or Ego-T at some point to save money/time/etc. And the V4L cartomizers I sold seem (thus far) to be holding up better than the cig2o ones... but is there anything I can do to avoid burning out the cig2o ones so quickly? It seems like (as someone who was less than a PAD smoker, about 4 packs of 100s a week) they die in much less than a day. I'll have to occasionally buy the overpriced, terrible cig2o carties, more likely than not, so I'm curious if anyone has suggestions.
