Took me a long time to come around to the DCT's. I always shied away because of the carto....carto's and I never got along well.
Found a shop and was able to give them a try....ya, Love!!! They are a pain to fill without a syringe, but manageable without.
Not had any flooding trouble. They really are part of my all day vaping collection. I have also learned how to punch an additional hole in the carto to help with wicking. The cartos usually only last me a couple weeks before the draw becomes stiff...their cheap so not a problem.
Use mine with my ego type batteries with a tube sock....give it a finished look. no gap between the battery and the tank.
Still love the clearomizers too...easy to fill, no hassel. been lucky, not had much trouble with them. once the threads get singed, burnt taste sticks around. have found that VG and darker liquids, seems to clog them up quickly.
I rotate regularly between the DCT's and the clearomizers....have to rotate to keep them from getting too hot...tend to vape ALOT!!
Then there is still my all time personal favorite....dripping...all around best throat hit, best vapor and best flavor. Mostlly drip while I'm at home...love dripping with the 306's. I have been dripping for 3 years and I think it will always be my favorite.
