2.2 GPM Faucet Aerator Insert, Small/Jr Size, 13/16-27 and 3/4-27, Aerated Bubble Stream,

Most of the aerators on Amazon are much less expensive, but this is the only "junior" one I could find with high flow rate. Didn't make much difference in my particular faucet.

Not as advertised. To help future buyers not get stuck with a useless $10 aerator, here are the ACTUAL measurements of this one:Diameter of white ring = 0.72 inches or 18.30 mmDiameter of top of grey piece = 0.685 inches or 17.42 mmDiameter of bottom of grey piece = 0.632 inches or 16.06 mmOverall height = 0.479 inches or 12.18 mmSo clearly, this will NOT fit in a 13/16" (0.8125 inches) faucet as advertised, and there is no bushing included to make it fit. Perhaps some faucets have looser tolerances and will accept a .72 or a .81 inch aerator, but certainly not mine, as it drops straight through.Since I was able to 3d print a bushing and make this fit, and I really like the flow it puts out, I am giving this item and extra star. Unfortunately, the really annoying whine it generates while running won't let me give it any more than 2 stars...

replaced the limed up aerator in my wife's sink in our bathroom. Now her sink flows as well as mine does. Parity has been restored and there is peace in the valley.

easy install and works like OEM

So glad to get these installed in my bathroom sinks. Previously had the green ones that only allowed a tiny trickle to flow. Now I get to decide how much water comes out of my faucet. So much freedom!

Satisfied

Works great. Definitely increased the pressure

Small jr size fit and is working great
