I'm on my second faucet of this style.  The first lasted a number of years. I have had trouble with the controls on the second since shortly after installation, but Moen has been good sending me free replacement parts.  What I love the most about this style was being able to disable the lower sensor and use the one up on the arc alone.  The lower sensor was too easily triggered.  The upper sensor placement was wonderful when handling raw meat or greasy foods.  I do not want a voice activated sensor.  I do not want to open my house to smart devices listening all the time.  The wave sensor alone is more appropriate.  This faucet is wonderful when it works as designed.
