Neoperl makes a good quality, modern aerator that is available in different flow rates and sizes. My only complaint is that there are no flats to put a wrench on. After these aerators that are perfectly round are on the faucet for a few years you often can't get them off by hand to clean them. A wrench is necessary and without flats for a crescent wrench you are forced to use pliers which will ruin the finish and leave jaw marks in it. This is a problem and a design flaw. Historically, most aerators came with flats for use with a wrench. I assume it is cheaper to manufacture them round with no flats. If so, this is yet another example of budget engineering in lieu of better quality.
I got a water conservation kit from PGE . I installed the faucet aerators and man they were loud.
You don't want to hear hissing everytie someone turns it on.
Went to HD and picked up a couple and installed.
Quiet and easy to install.
