Today I got my Vapefly Wormhole RDA and all I can say is WOW! This RDA is amazing so far. I threw in some round wire SS 316L 3mm id 8 wrap coils .19 ohms. Running in tc 60 watts 430°F. The flavor is amazing with thick dense clouds. I have the inside airflow wide open and one hole cutoff on the side airflow. I'm using Vapetasia pineapple express ejuice 3mg. My favorite RDA is my Lucid but I think the Wormhole might take the #1 spot. I'll use it this week and throw in some fused claptons this weekend.
