Query: Poor quality/quality control.

Functionally, the unit works fine. But on installation, one of the holes in the plastic base plate had to be reamed out to size so that the tiny screw holding the face plate could be screwed in, making the installation unnecessarily tedious. In addition, the metal nut securing the timer face plate threads onto a plastic bush. You cannot thread it on with your fingers because of the recessing. But even with very little torque using a pair of pliers, the metal nut stripped the plastic threads at very low pressure. Why use a cheap plastic bushing instead of a metal one? (obviously, to save costs). My first reaction was "More cheap Chinese imports", but in fact it proudly proclaims "Made in USA"!
