i picked these up after purchasing a joyetech evic vt. i was using the nickel and titanium coils but wanted a rebuildable option.
comes apart so you dont have to mess with fishing the coil through the top or small opening
cool design for rba section
easy to wick and coil
really small, smallest rba i've ever built on
the top hat of the head got stuck in the chimney section when i went to refill it
still i would definitely recommend to anyone that has a compatible device
