We had to replace this faucet after only three years. It would not swing side to side any longer, so we ordered a replacement O-ring and new bonnet. The hub assembly was pitted and corroded. We realized we would not get a good seal with so much pitting so we purchased a new faucet. The other issue was it was a pain to put handle back into hub after pulling it out to spray. It was keyed and did not lock into place unless you used two hands. We replaced it with the Delta Charmaine model which has the magna-tite wand attachment to hub. Hopefully this one will last longer - will let you know.
