INSTANT-OFF ECO Water Saver Automatically Shuts Off Water! Replaces Aerator, Reduces the spread of germs, Stops Drippy Faucets, Option for continuous water flow.

I love these. I once had a Lixit on my outside sillcock which operated very smoothly and was solid metal (it is a gadget to give a dog an constant automatic source of clean water). These are similar but for handwashing sinks. Pros: Help keep sink clean, easy to use, stops drips, saves water, never have to touch faucet handles. Cons: All the negative commenters here are likely using the "continuous" flow model which is problematic. You want to buy the "AUTOMATIC" only model, with steel rod, which is absolutely flawless, It has a particular model number which I can't remember (150 maybe? NOT CFLOW). I have been using them for years on various faucets, none of the other brands/styles work reliably like these do, I have tried just about every one on the market. NOTE: These can cause "plumbing crossover"; in mixer faucets if both taps are open, only one tap should be open at a time. Possible effects of plumbing crossover; are large amounts of wasted heat in hot water line, possible scalding, downline showers or taps that are slow to heat up and never get hot as normal, severe conditions could even cause a toilet to crack. So be sure to only open one tap either hot or cold but not both at the same time.

This greatly exceeded my expectations. It is pure simplicity and works like a charm. I live on a boat so I need to haul my water to the boat and this really helps me conserve water. Touch it and it’s on. Only a few drips of water are wasted each time you use it instead of having to turn the faucet on and off. Highly recommended.

This a wonderful solution for dripping faucet. It is also a water saving instrument. The water flow from the faucet should be adusted not to resonate!

So far I love it. The product appears to be durable, it has both male and female threads so it can be used with any standard sprayer. It's simple, leak proof and has already proven its value for the short time that I have had it. I would totally recommend

It would not work with the kind of faucet I have. I would not recommend it. They make it seem so cool, but it isn't.

Works well for adults trying to save water, not so much for childproofing. Three weeks after install, my pre-schooler has defeated it. This time I'm going with with the free solution of just turning off the water to that sink.

It was EXACTLY what I was looking for. Fits perfectly and easily onto the taps. Will help save loads of water. While the protuding white stick may not be the most aesthetically appealing, it makes getting the water to flow really easy (as compared to other water saving devices I have used which required me to push a short stopper into the tap). For this, one easy nudge against the stick and the water flows. I am so pleased. So is my hubby! Glad that Amazon ships this to Asia where I live.

I am simply thrilled with this product as it works with my Pur Water Filter too!! It took no time to install. It is great for my husband who has dementia and now I do not have to worry about an over flowing sink or a flooded floor. Thank you
