Waternymph NSF Certified Dual-function 2-Flow Kitchen Sink Aerator, 360-Degree Swivel Faucet Aerator Dual Sprayer, with Gasket Faucet Replacement Part - 55/64 Inch-27UNS Female Thread - Chrome- Swivel

This faucet attachment is simple and durable. Made of material that will ensure it will last and looks like high end product cause it is.

So, I've been very happy with this. The structure of it is tough, clean, well made, and better made than other aerators I have had in the past. It came with more accessories than the others I have had too, as there was a gasket, and both female and male options to use. The only thing I noticed was that the depth of the threading fell a little short of my faucet, leaving just a few threads exposed.I really was looking 100% for function and that it did not leak from the threading no-matter-what: I got both. If two threads stick out but no leaks and I can push it around without babying it while washing veggies and dishes, I'm pretty good with that. I've had prettier aerators with perfect fit that "worked themselves loose" over time and leaked. This one does not.I had a standard aerator on my faucet, which I believe now actually throttled down the water pressure to a level of very frustrating. I mean, if there is pressure X available through your pipes, I expect that same pressure to help me speed up washing dishes etc. I was thinking the pressure in our unit was just semi-dud. Until I screwed this thing on it. Talk about going from VW to Nascar... Love this thing!So everything is a trade off, and I'll take well-built, sturdy, snug, no mess no surprises anyday, to just a smidge off of "perfect appearance". I don't have many visitors who stand there and inspect my kitchen hardware while we chat it up. I've uploaded 3 pictures to show. It is highly zoomed, so honestly standing washing dishes you can hardly even notice it. But...So it comes with a male attachment kind of thing, or female. I needed the one that screws over the threads on my faucet. So to fit, that relies upon both a diameter/screw size, and threads-per-inch. I've purchased items before that failed one, the other, or both. This one fit in both, has not an ounce of leaking, is tight enough to be sturdy without leaking, while "not so tight" that I cannot take it off. I did not have to use a wrench to put it on, only hand twisting. So it fit well in those respects. What did not fit well was the depth. It fits snug as I shared, but stopped just short of covering all the threads.In the pictures, the first shows faucet off, threads showing.The second shows one of two sprays: The standard spray, like I had before, only many times stronger and now I can speed through washing dishes and fresh broccoli in no time without having to treat the aerator "gently" :) It seems tough! I shared this to show there isn't any chance of this leaking... it just doesn't.The third and final image, shows the second of two sprays: The spray that spreads out and enables me to get lots rinsed fast... See the threads. It doesn't leak either.It sounds not at all too exciting to share this, I understand. Why did I invest time in this? Because I was reallllllly impressed to get an email, after I had used it for days, from the seller, concerned that there had been some "sizing issues" reported, and offering to assist. I was thrilled with this. But for a seller to go out of their way to try to help when they could have done nothing? It just struck me as really impressive. And every time that happens, I have that ounce more of faith in buying at Amazon.So shoppers: Please take a look at the pictures, consider how zoomed they are, imagine how backing off from them would hardly notice any irregularity, and the reasonable $15 price paid here. I've got several times the water pressure I had before, absolutely no leaks, no difficulty screwing it on/off, and I'm washing veggies like a monster again.Finally, I will share when I need another of these, I will look for this make first. I've had cheaper, plastic-parts, less aeration, loosening and spritzin water with these things before. I'm kinda spoiled now. And happy with that.Wishing all well!
