I ordered these manifolds, the older "Q" versions are no longer available, and I have concerns with the "LF" version. The ball valves have rather sloppy action at the lever. I contacted PexSupply and they are aware of this, but so far, they've gotten no response from Uponor, and neither have I:

I'm trying to figure out if these valves are going to leak, before I solder in the manifold. Anyone have experience with this?
