Ok, got mine on yesterday. I want to get a couple of things in here.
Someone mentioned that the little plastic pipe it's attached to could come loose. That's the exact problem we had with mine. Nothing some fresh epoxy and a small clamp couldn't fix.
Are they testing out any more? No, they have pretty much what they need to develop the final product. It should be coming out very soon (I beleive within a month). Pricing, I'm not sure of. But it will be competitive.
The turkey is still audible, albeit drowned out by the BOV.
And yes, it sounds nice at 10psi.
