According to my contractor, easy installation and a good quality product. It looks great and appears sturdy and long lasting with smooth lever function. Just a couple problems: 1) The water flow is very pressurized and highly aerated. Even though I have a deep sink, it tends to splash off things and onto the counter top. I eventually lessened this problem by closing the water valves partially to restrict the water flow. 2) There is no on/off button for the pull-out sprayer. The water flow is the same as when not using it hand-held. Because of the pressure mentioned above, this isn't a major issue. But it wasn't what I expected. Overall, pleased with the product. Sprayer is spring retracted, which makes it a little tough to pull out but ensures it always retracts completely. Had an old retractable that would jump out a half inch when you turned the water on and off. No such problems here.
