I am not a fan of infrared faucets - it completely strips away control from the user.
You can't dictate the amount of water - whether you want a trickle or a gush of water. You can't dictate if you just want to leave it on (for whatever reason) unless you leave your hands in that magical spot. O the magical spot, waving around your hands around the sink, feeling like a total idiot (not to mention learning the magical spot of different infrared faucets, since I'm seeing them in public restrooms and airports now), and if your hand leaves the beam for just a millisecond, the water shuts off, then you wave your soap covered hands around feeling like a bigger idiot.
Infrared is way too niche and 1 settings only.
