what PMW said......
with the 18mm sovereignty the thing has crazy good airflow.... You literally have to pull your breath enough to bring the water level down to the bottom of the stemless diffuser and all the smoke just comes around and falls UP the tube..... it's really a great every-day experience...... the oil is much more airy and diffused.... tastes smoother, cleaner and less stuffy out of my soverignty...
that doesn't even touch on how easy it is to clean either.... I put on my 18mm stopper (from dankshizzle
) fill up with ISO and Salt and swish for 4 minutes and its spotless..... don't have to take any stems out and wipe down the outside, it's just all one + the dome / male + male adapter.....
