Since 2013 I had the 2 sensor touchless kitchen faucet by Moen.  Worked flawlessly but it went with the house when I sold it.  In my new house now and thought I would try the one sensor voice controlled kitchen faucet.  I do like the features but I am on the fence whether or not I should have again purchased the 2 sensor model.  I find I do not use the voice operation that much and miss the momentary on with the 2 sensor model.  Unfortunately, I cannot return the voice model.
