Installed product and:
1.  The braided hot water hose kinked while attaching it to the hot/cold water valve.  The end was not fully engaged when the hose folded.

2.  The drain lift knob does not remain on shaft.  The set screw advances and should be adequate to lock onto the valve shaft, but it does not.  It continually fell off.  Eventually, I used super glue to get it to stay in place and activate the drain.

I love the simple clean design of this unit, but the component material/build quality is terrible.  I would avoid this item at all costs.  I will avoid this brand going forward.
