I'm giving it four stars because I've never seen an aerator that comes within the end of the faucet that you already have and the faucet end is not broken. I now have two bronze faucet ends, one with a working aerator. The aerator itself cannot be purchased alone. I even went to Delta. Aerators alone are usually 5.00. This was not 5.00 but Wayfair had it for a good price. Works just like it did when I first bought it 13 years ago.
