I just used a micro coil with a hemp fiber wick. Didn't like the condition of the SS mesh tank wicks that came with it, so rolled up some fresh SS mesh tightly, and left them a tad long in the tank side, thinking I would help felicitate the wicking to the coil wick. Have had it up to 20 watts and wicks well this way. It reminds me of a tiny Flash-e-vapor V2 rba/rda. Sure is plumbed the same way. Decent slim rba.
I vape 70-80% VG juice and never a dry hit. Works great for me, but am use to building the Flashi.
