I bought and installed this just before Thanksgiving 2019. I bought it because of the features and knowing that Delta is a good brand. We were very happy with it until April. Then it  it started acting up. We've replaced the cartridge cleaned the head and still the same issue. The water pressure either drops during use or is low from the start. This makes this unit worthless right now. I had a plain jane faucet for from 1997 until we replaces it with theis faucet and had zero problems. I cant believe that in 6 months the water in NYC somehow doesnt work w/this unit.
