Pull out handle is plastic. Rest of faucet is metal.
I'll start with the negatives:
The two buttons on the pull out (one switches to spray mode, the other "pauses" the water flow) both started to fall out all the time after 6 months. Eventually they stopped going back in (after 18 months).
At 3.5 years, the faucet will only work in spray mode. In order to get it back to laminar mode I need a pair of needle nose pliers.
I'm filing a warranty claim.
Positives:
Looks good and is fairly easy to clean.
Temperature and pressure control is intuitive.
High arch is out of the way when cleaning large pots.
