Niagara Conservation N3610CH Tri-Max 1-Spray 0.5-1.5 GPM 1.4-in. Pressure-Compensating Needle-Spray Faucet Aerator Chrome | Bathroom Sink and Kitchen Sink Aerator for Home Improvement

This is an awesome product. For just a few dollars you have an easy-to-use device that can save money and gallons of water effortlessly. And for people in your household that aren't as ecologically inclined as you, they can just set it to the max setting so it's not like this thing is really a burden on anyone. It's also extremely easy and intuitive to switch between the three settings.Just based on some very rough calculations, every six minutes one of these aerators is set to the lowest setting necessary, an entire five-gallon jug of water is saved! Going with this math, we found that the aerator would pay for itself in a relatively short period of time.Installation is easy. In general, you need no tools but there can be some exceptions. For instance, if your old aerator is ancient and happens to be stuck on the faucet, you would then need a wrench to get it off. (The conventional advice is to first wrap the aerator with a towel so it doesn't get scratched up by your tools.) You can even install this thing on marginally irregular faucets. We had a faucet with an overhanging lip that was way too long, but we managed to screw this in by squeezing the bottom of the aerator and the top of the faucet with a wrench, and then screwing it in normally.The higher settings tend to produce needle-like water that comes out pretty fast. Depending on your preferences, this is either an advantage or a disadvantage. I personally like it. It's rarely inconvenient, and there are a number of situations where it is useful to have the water do this.Now for some drawbacks that in my opinion do not take away from the five-star rating:• On different faucets, the aerator appears to yield different water pressures. (However, on each individual faucet the three settings still yield water pressures which increase or decrease based on the setting.)• On one of our faucets, the aerator makes a high pitched squeal on the lowest setting. This is mildly undesirable, but something we easily live with.• On a very old faucet, this aerator somehow caused a water leak in the faucet itself, and we had to replace the faucet. This faucet was extremely old, so we don't really blame the aerator.• On rare occasions the silver part of the aerator will slip off when you change the setting. It's easy to snap back on however. I've only seen this happen with one of these aerators, and once you realize you shouldn't tug downwards when changing settings, you pretty much stop doing it.I highly recommend this product!

Kitchen sink already had a nice expensive double SS sink and quality faucet - just move into this house last year - and the end of the faucet's swivel spout has a pull-out end with a flexible hose to squirt around the sinks. The stream was solid and my wife wanted a shower stream effect as an option. I took the existing (plain) aerator off and installed a Neoperl Bubble Stream Dual-flow Aerator that I bought at one of the local (national chain) hardware stores...at the same time I ordered a Niagra Tri-Max Aerator. The Bubble Stream Dual-flow Aerator was supposed to have 0.5 gpm spray or a 2.2 gpm stream. We used this for about a month or so (until today) and we found the spray very weak, and the stream also pretty weak. (I don't think it was anything like 2.2 gpm.) Turning on the water, you got the spray by default and you had to pull down on the head of the unit to get the stream. Most times pulling down just dislodged the faucet nozzle's end hose unit from it's seating and you still had the faucet spraying. It generally took two hands to get the stream (which, as I said was very weak). Today I installed the Niagra unit - what a change! Now to change the flow it is a simple twist on the head of the unit! (The hose and head don't accidentally dislodge now!) and the 0.5 gpm is much stronger than the previous unit's 0.5 gpm shower, AND it's a more concentrated (narrow) spray pattern. (The previous unit's shower was much more dispersed and it "kind of showered everywhere!") The Niagra's other two settings of 1.0 and 1.5 gpm are both stronger than the other unit's 2.2 gpm stream. It should be noted that the Niagra's two stronger settings are both showers - there is no stream - but with the more concentrated spray pattern, there is less splashing..and my wife is OK with no actual stream setting. Anyway, it's the better aerator and it gets a full 5 stars.

So this does exactly what I expected it to and it does it well. It saves me water and it actually feels like it increases the water pressure. Some things that may bother others:1. The installation can be a bit weird with the key they give to screw in the adapter, but I was still done in under a minute.2. The majority of the construction is plastic. All appears to be good enough quality.3. This product sticks out a bit further than my previous aerator did, but my faucet and sink provide for enough room still that this isn't a concern for me.4. As noted in some other reviews, the selector can pop off fairly easily, but also as noted in other reviews this makes sense and it is not like it is straight up falling off the faucet.5. Also as noted elsewhere here, the only mode you've got is the needle spray. I thought this might bother me, but after washing my hands in that sink, it does not. If you're feeling it is too weak though, just dial it up to the 1.5 or 2 setting and you're golden.

It was a little tougher than expected to get it to not leak when connected, but after tweaking the rubber washer type and thickness it's been fine. The super low flow is perfect for rinsing , while still being able to dial up the pressure when needed for filling pots. I've also noticed 10-15$ drop per month in my water bill because of the.8 GPM setting.After months of use I've had zero issues .
