The plug worked fine but I was disappointed I even had to order it. It’s just a piece of plastic with an o-ring. It should have been included with the faucet. Anyone who has an under the sink filter system has no use for a spray nozzle. I’m also disappointed I can’t order the faucet aerator without the chrome piece it fits in. The price is too high for a part that gets replaced often and There is no need to replace the chrome piece every time.
