Moen Aerator Metal

Excellent assist. Ordered aerators they were too large. Company immediately sent out next size down which fit perfectly. They could not have made it easier.

The problem with this product is the original aerator design. After time, the grooves the key is supposed grab on to are mineralized and corroded. The key isn't able to get a good grip. Perhaps making a metal key would be improvement. It's also difficult to see what your doing trying to access the underside of the faucet on a small hand sink. Would not have bought the faucet had I realized how difficult it is to replace the aerator.
