This was a replacement for an older model "Renzo" from 2013, which had cracked (plastic then) spout retainer. Customer service was great!! New models have beautiful stainless steel spout retainers and many other subtle but good design alterations. Spout itself still plastic. Pull-out of spray head much improved, nice flow. Kit comes with about all one needs, save for a couple of very basic tools. Very good instructions. Was replacing similar model, so in this case install was very smooth. (Last time installed shut off valves which made things a bit more complex, but highly recommend having them). Only reason for 4 stars on durability is that spout is still plastic, but may do fine. Highly recommended.
