I purchased the eleaf mini Pico. Was not real happy with the RDA that came with it because the air flow slots are at the bottom and when you squank the Box, the juice comes out the air flow. Juice everywhere all the time a nd I’m only squeezing the bottle 3-4 times. I went out and purchased a velocity RDA. Fitz and works just great but the .19 build on it won’t fire. Works great on my Reuleaux but not the Pico. I’m guessing since the Pico only uses one 18650 battery the build is too low. I am new to Dripping so am I correct in assuming what I’m assuming? Thanks in advance for the advice!
