Neoperl 13 0000 5 Standard Flow Cache Perlator HC Aerator, Tom Thumb Size, 2.2 GPM, Red Dome, Honeycomb Screen, Aerated Stream, M16.5 x 1 Threads, Plastic, 0.591" Height

Fit perfectly and allowed for good water flow. Could not find these at any of our local Lowes, Home Depot, or ACE Hardware stores.

Flow rate is slower than what I get from my stock 1.2 gpm aerator. Brizo faucet.Stock aerator allows 1.0 gpm in my setup. This new aerator allows 0.85 gpm.Whole purpose of purchasing this gadget is to get the higher flow rate. This didn’t perform.Did I get a bum unit? Dunno. All things scaled, it’s acting like a 1.0 gpm aerator, not a 2.2 gpm.

Allowed water to flow again without restriction which triggered the water heater to work better.

Replacing a blocked-up aerator in an old faucet. I dislike this style in general, but this works as it should. Nice touch to include a key for install/removal for people who don't already have one. Only gave 4 stars as $9 for this little item is a bit expensive in my opinion.

It arrived quickly, and was an easy swap, however, the flow wasn't as advertised. My original aerator was 1.8 gpm, and this new "2.2 gpm" aerator was actually slower. I tested it against a different faucet that is 1.2 gpm, and it was almost identical in the time it took to fill my test container.

These Tom Thumb are smaller than the others and were a perfect fit for my faucets.

Works as described easy to install, with the included color matched tool set. Wow thanks for that!!! I really like the increased flow, with the aeriated stream.

This items works but has less flow than the 1.2 gpm stock Delta aerator.
