I can confirm that the Joyetech Cubis RBA does indeed work with the Mi One, and works well at that. Pretty sweet that you can rebuild and refill something this small. Also, I’ve heard lots of people saying the airflow adjustment doesn’t make a difference, but the one I received from Element had the “upgraded” airflow apparatus, and it goes from so-tight-you-can’t-draw all the way up to restricted DL, and everything in between. I wasn’t sure so I went on the Smoking Vapor website and bought the upgraded airflow kit, and it’s identical to the one I received with the starter kit, except that it’s black in color. I’m really digging this thing, much different from my usual mech mod and RDA setup, but perfect for situations where you don’t want to cloud up the whole room.
