The Delta 9197T-AR-PR-DST is a beautiful faucet.  It was so easy to install.  The directions were simple and easy to understand. The touch technology is so awesome, no messy clean up.  The pull out spout is a heaven send to rinse dishes the shield spray keeps the water in the sinks instead of on you. The automatic water shut off after four min. And the LED light is red if water temp. Is hot and blue for cold also helps when you have kids.  Very cool features.  Absolutely a beautiful and functional product.  I will recommend.
