Turning on for the first time I listened very close for the characteristic hiss or Pop from over aggressive heating elements - NONE Totally quiet! and the Heat time was very reasonable even quick - Temperature control very smooth with plenty of range.

Review: Use 2 of these in different ways, excellent results! - I purchased one of these for my Florida office and it works extremely well to deliver instant hot water for hand washing, etc. I purchased another one as a pre-heater for an addition on home with long lines to the primary hot water tank. This works superbly! Instant hot water for hand washing, instant hot water for shower until the main hot water tank takes over. For the shower, the cold inlet comes from the main heater tank and the outlet feeds the shower and wash basin. Works very well, saves time and water because you needn't let the faucet run and wait for hot water to come from main tank. Love the results! Excellent product and excellent results!

### ⭐ Cheap fittings included in the package.
*by J***. on December 16, 2020*

Purchased. Had a plumber stop by to install although it appeared to be a simple installation. Plumber left and water heated up. However, after a couple of hours one of the fittings included in the package simple broke where the treads connect to the housing of the fitting. Obviously, water flooded our kitchen and my wife and I spent a couple of hours cleaning up the mess after we were able to shut off the water supply. Thankfully, we were present when it happened or there would have been major damage to our home. We have now called back the plumber and instructed him to replace not only the broken fitting, but also the other fitting as well. These are cheaply made brass-like fittings and I do not want to have to worry about them breaking again, so I'm replacing them with quality fitting. Suggest you do the same if purchasing any of these units that come with fittings.
