Bests & Worsts Reviews from Amazon

I can't speak to the longevity yet but so far I should have put this in years ago. Instant hot water to the kitchen sink which is over 40 feet from the main hot water tank. With the plumbing running through the crawlspace I used to have to wait a minute or two for hot water. Not any more! The kill-a-watt electricity meter told me it will cost me $25-$30 to run over the course of a year. I mounted it inline on the hot water side in the crawlspace but still under the kitchen sink to save room on the main floor. I used a couple sharkbite connectors and flexible hoses to hook it up. I bought an adapter to mount a garden hose thread (GHT) to the overflow into a 5 gallon bucket.
