I purchased this model Delta to replace a 36 year old Delta Classic 2-Handle Std. Chrome Kitchen Faucet w/side sprayer and plastic knobs.  Installation 2-weeks ago following the provided directions was pretty simple.  The feature I like is the ease of operation, which only takes a gentle motion with a pinky finger.  Also, I like that it can be operated with the back of your hand if your hands are sticky from cooking in the kitchen.  The aerator and screen was easy to remove and replace with one that connects to my portable dishwasher and this was convenient.  I also really like that this unit is not huge in size like some modern model faucets, and that it is unobtrusive to the eye in the kitchen.  It functions nicely and is a beauty.
