We have been remodeling our kitchen, and hesitated to purchase this because there were several questionable reviews.  The price was right, so we purchased.  Oh my stars, I love tit!  I have realized how often I need to turn on and off when my hands are dirty or wet.  It always works!  I would love to have all of my faucets with the touch20 technology.  We did take one of the reviews advice and installed the batteries in the front for an easy change.  Totally recommend this product!
