          It does what it is supposed to - It’s worth it
          This recirculating pump is definitely worth it. I was a little unsure how much difference this could make, it works really well. We installed an on demand water heater in our old house. It took a long time for the farthest faucets to get hot water. This is installed under the kitchen sink. It not only brings hot water to that faucet much quicker, but it also makes hot water available at all of the faucets in the house significantly quicker than before.

          I installed this in our master bathroom vanity sink area. Before I had this, it would take several minutes running the water before the hot water would arrive at the shower, wasting a lot of water. Now, I push the button, and after a few minutes, the pump stops and the water arrives in the master shower within 5-6 seconds. I created a YouTube video after installing it if you want to see the results. This is a super high quality, easy install for DIU homeowner with basic skills. https://www.youtube.com/watch?v=NqfhvFCCdQI&t=11s

            Kit had all parts needed for a quick and easy install. I run it through an Alexa enabled plug in my kitchen. It provides hot water in less than 2 minutes run time. Before installation I had to run through about 3 gallons of water before my tankless water heater would provide hot water at the tap.

            Buy your own "tees"
            Buy 2 brass 1/2" male thread tees. Run the 1/2" supply line from the angle/strait valve to 1 male, run the pump supply line to 1 male, buy a 1/2 FIP X 1/2 FIP X 20" supply line and run it from the final male and up to the sink. Now you have a functional system isolated and shut off using your existing angle/strait valves!!! Soo much simpler/easier!! The really hard (or just tricky) part is providing power to the pump. Most lav/vanities in bathrooms have no power receptacles inside them.

              Easy Install under bathroom sink saves time waiting for hot water where I need it - shower.
              This replaced the Auto Circ that we had installed ~17 years ago. A replacement of that brand would have cost me more than $900. That one died due to the button wires worked loose and ruined the electronics. I kept the original pipes and swapped it out easily. Just ensure you completely shut off the water to your house.

              Very quiet. Needs better instructions. Make sure to use compression t-fittings so that you can twist the orientation of the pipe hookups.if you use your own screw in t-fittings, they might not orient correctly

              No Warrantee
              Product worked great for 15 months, then failed. TacoGenie (manufacturer) Technical support agreed product should be replaced, but Rheem should handle it. Rheem and was unable to find anyone who knew what the product was, much less willing to warrantee it. They finally gave up and referred me back to TacoGenie. Went to Home Depot for help. Customer Service spent more than 3 hours valiantly trying to help with calls to TacoGenie, Rheem, distributers all to no avail.
