As I said, I had trouble with mine - it took quite a bit of experimentation with O-rings. But I have it fitting the 8m adapter now, which I have fitting my Revolve stem; I also have the Stunner set up with the older (carb hole) version of the Dani wood stem, which works really well... but it's going to be a pain in the ass to clean. So this has ended up being a catalyst for a 2nd Revolve stem. I was already thinking about it, cos I love it so much, and it's the easiest thing to clean that I can use with the Stunner.
(I have no idea why it fits the old wood stem and not the new titanium stem, but it's not even close, it falls out almost without any resistance. Fortunately I don't love new Dani titanium stem and haven't found myself using it for the Dani Fusion 2.0 either.)
The biggest problem I'm now having is overheating. It doesn't turn to ash when it combusts like a Dynavap, but it happens so quickly and tastes so gross when it happens, and you're just left with a combusted black plug.
