That's why drippers tend to love vacuum tank RBA's. The kayfuns being the more popular...more affordable..option. I love drippers, but I would wager that I get more flavor out of my kayfuns. The vacuum you create while pulling is bringing fresh liquid into the wicks, so you're not just relying on capillary function of the wick laying on a deck to absorb liquid. I love hearing the bubbling of a kayfun. Then, the vacuum in the tank keeps the liquid from continuing its flow in the evaporation chamber..Perfection*
If you cycle through a lot of flavors, I suggest a dripper for your first RBA. If you can stick with a flavor for 1-3.5mL, try a kayfun or other vacuum tank atomizer. Clones are cheap, and a good way to see if you want to pursue the original version. Plus, I was a little deterred about getting one. When everything is disassembled, it may look a little complicated, but it's actually the most fuss free vape I've found. If you use rolled cotton or cotton balls, go to the kayfun threads in assorted PV topics>>Rebuildable atomizers. I was about to go crazy following build videos to the 'T,' and still having leaks.
