I have to say I was pretty skeptical, I opened the box read the not so good instructions, I told myself to return it. The faucet is beautiful and well made, What a pity I said. Then I watch the video on Amazon, I think I got the gist of it so I decided to install it. I took a lots of effort to remove the old faucet, installed this ones is so easy. First mount the faucet , then connect the water lines to the T connector, connect the middle connector to the IN control box, connect the OUT to the line from the faucet, screw in the black wire and plug in the red wire, connect the control to the power source. Bingo!You have to put your hand close to the faucet mouth for it to work.Use the knob on the T connector to adjust water temperature. That’s it. If I can do it so do you. I love it
