We were very excited to install this faucet and Delta made it super easy by the included paper instructions but also by the assistance of their video posted online.  In total, from the start of removing our old faucet to the end of installing the new one, it took a little over one hour.  The faucet has really nice features including the new spray function that creates a shield of water around a single power stream.  This blasts through stuck on food and keeps your shirt dry in the process!  Very nice!!  The faucet also has a light indicator that changes color with temperature to give you a visual reminder of how hot or cold your water is.  Overall we are very pleased with the install and the functionality and would absolutely recommend this faucet to others.
