We purchased this faucet a few weeks ago and so far it works as advertised. Just wave your hand over the sensor to turn on and wave again to turn off.
Installation was simple and directions were easy to follow. All the supply lines were included, so no need to run to the hardware store. I installed this myself and took my time doing it. The entire process took about an hour. The only annoying part of the installation was: the supplied nut used to secure the faucet to the underside of the counter, was filled with a heavy residue and wouldn't easily thread onto the stem. It was an extensive clean with my Dremell brush attachment, but if I wouldn't have had a Dremmel, I probably would have needed to ask for a replacement. It was a bad QC issue in my opinion. Other than that, it was a simple install.
Overall, very satisfied with our purchase
