It's very "chuggy" sounding. When I'm actually taking a hit and the airflow is more restricted, the sound makes me think about a hovering helicopter. Still, the draw feels very light to me, even with all that water. But, like I said...not much to compare it too.
Obviously, with all that water there is kind of a sweet spot with the amount of pressure I use on the intake and on clearing it. You can certainly get a mouth full of water quite easily, which I have done more than a few times. But after a month, I don't even think about it anymore, its all automatic.
Your just going to have to experiment and see where you like the water level. I will say there is definitely a minimum water level. Those videos you see of people sucking air into the recycler drain have the water level too low.
As far as the glitter goes...still finding that crap everywhere. Never again!
@Cannabis Connoisseur I definitely want to hear what you think once you have had some time with it. Be nice to hear how it compares to some of the other pieces you have.
