You are saying you just put the QD on open with nothing connected to it to let it settle? The beer I'm drinking now started out like shaving cream. I pulled the pressure release a couple of times and hooked it up without the gas connected. Now it's still pretty fuzzy but settles down nicely. That rarely works for me.
I thought maybe the spunding valve would have let just enough out to fix it. Gotta wonder if you would have to set it high first so there wasn't such a fast blow out that foam and beer blew out. Then gradually dial it down until it reached 12psi or so.
Still hoping someone bought one of the ones I linked on Amazon to get a better review. Guess I can always get one and if it sucks send it back.
