This is the favorite thing I bought for my kitchen remodel.  Sure, it's expensive but to me, it's worth every penny.  It works great and is so pretty!  I love not having to touch the faucet handle with my dirty, cooking hands.  It also helps prevent germs from spreading.  However, when it was first installed, it wouldn't turn on until I played with the sensor (covering it with my finger).  And then, it came on a few times sporadically.  But after that weird start, it has worked perfectly for weeks now.  Highly recommend!
