Mine arrived about two weeks ago and I must say Im pretty happy. Been using the
rba with dual coil clapton at around 40w. The airflow ist much better for lung hits than the single coil RBA. Maybe a little bit more airflow than the newest stock
coils.
The only thing I really dislike is the drip tip! I would not use the airflow on it and keep it closed all the time, but it leaks through the airflow slots. The chimney is pretty narrow, so with the Top- and Subtanks I´m used to a little bit of liquid in the lower part of the drip tip, but with this airflow drip tip design that becomes a problem. It gets to my lips. And to make things worse: The drip tips of my Toptank Mini and go One Mega do not fit. Bummer.
Otherwise and in total I´m very happy. I paid around 17 to 18 Euro with shipping from vaporwhale. Great bargain!
