Bought this for our American Standard kitchen faucet. Absolutely the best swivel aerator! Can choose between either rose spray or the gentle aerated stream by simply pulling up/down on the outer sleeve of the aerator. And the rose spray pattern is like a rain pattern, not the circle pattern produced by most all other aerators. Pricey, yes, but worth every penny. Made in America by Fisher Manufacturing, serving the plumbing needs of restaurants, etc., but this aerator fit right onto our kitchen faucet. Have used Faucet Queen and various cheapies from Home Depot and Ace and generally disappointed. We, so far, have been very happy with our aerator.
