nice 19 mm rda, a quite airy MTL. I use it exclusively in squonking mode from time to time. it's a great flavor RDA and contrary to what one may think at first glance it's not that so prone to leak after a familiarization period. (ok it won't leak unless you overdrip, but this can always happen, at least at first. and then, this one is likely to cause real flooding, believe me! :)
And through this, it's a very nice flavor chucker. In addition the deck makes building a breeze. However, in this class, I prefer the "le Papillon" (16mm) or the Speed Revolution (18mm) with a slightly enlarged airflow.
