Have had three of these installed by professional plumber 7 years ago.  Each one has been problematic.  Spout eroded down to the metal - now it's just ugly; handle scratched over time even though never used anything harsher than vinegar; handle became harder to operate over time; handle loose and could not be tightened, set screw stripped very easily - not stuck with floppy handle.  Cleaning was always a chore, hard water deposits got under handle.  Replacement parts were provided, but will be replacing this with something other than this model.
