I just installed this faucet as a replacement for another spray faucet I installed last month. I wanted a pull "down" vs. "pull-out (more horizontal)" sprayer I found awkward. Fairly easy, BUT at almost the last step (re-attaching the water supply lines) I discovered they were ~3" too short?? With my other unit they were too long. I don't have a large fancy sink, so not sure why, but I had to make a trip to the hardware store to get additional length of lines (adding additional possible "leak" connector points). ALSO, I was forced to adjust the angle of the base so the handle had room to reach full range for the hot water. It's a bit off kilter, but works to clear my window ledge. So far the sensor feature and sprayer pull on/off is great. Hoping all the connections remain leak free.
