Things have been pretty consistent, haven't had any issues from the unit. One of the heads is a tad loud but I can't really hear it unless my head is inside the sump area.
I just passed on a deal for a unit. Borrowing a brs and then I'm gonna revisit the marine magic doser or possibly look into the jebao 4 head unit. Glad to hear yours is a good unit. My sump sounds like rapids so I wouldn't here it, lol.
I love their pumps and couldn't pull the trigger on a jebao gb we had local. Now I'm kicking myself for not finding a way. I'm gonna be honest and say I'm already leaning towards the jebao unit just because on my wp40s.
