Great RTA
Upon receiving this it was quite pleasant to use easy to build and wick has airflow options for your liking to use I left the inserts out and use it as a restricted dl tank even though it supposed to be a MTL RTA I've had no leaking issues whatsoever on it has been proforming great for me the way I vape so can't really say much on the airflow inserts it was a great buy for me and get decent vapor production off it and the flavor is great on it but that's subjective to your builds n juices since everyone taste is different
