Review: Works well, but damaged in product box by some careless engineering. - Item arrived and I unboxed it to find that the case face was damaged and 3 of the 4 machine screws that are supposed to hold the heating element down were loose and rattling around inside, which left me very unimpressed. The heating element is currently held down by four machine screws that screw into sheet metal brackets welded to the case back. I suspect that, due to the weight of the heating element and maybe some rough handling after manufacture, these machine screws worked them self out (one actually did strip altogether) and then one or more got trapped between the heating element and the case front. In communication with the sellers (who are very good, BTW), I suggested that instead of just relying on the bracket to hold such a heavy component, that each bracket should also have a clip nut. I also asked for a replacement front cover, but accepted a $20 goodwill refund when told that none was available. So I hooked the unit up and it actually works quite well. The thermostat seems to be a bit of a wild card, and I haven't played around with it enough yet to figure out if it's over-reading or not, but it appears to be 10 degrees off (higher) than the actual water temperature at the tap. To see if at least some of that temperature loss is between the heater and the tap (which is about 50 feet away - had to put the unit where I currently had 240v for now) I would need to disconnect the hot side again, which I may or may not do. Also, after a bunch of messing around trying to increase the indicated water flow (which, for me, eventually maxed out at 1.4gpm), I am now under the very distinct impression that this unit is incapable of delivering more than 1.5gpm, which is admittedly all the manufacturer claims in at least some of their product info., But, still, they do persist in showing 1.8gpm in all the pictures of the unit and claim a theoretical 1.8gpm in the manual. Certainly I have enough delivery for hand washing but doubt the unit would be acceptable for showering. Please feel free to comment if you have the same unit and are doing better with it (commenting requires a computer - the app does not support this feature). Upate: Unit has failed today with an E2 error code that comes up moment the unit has power applied to it after resetting via the circuit breaker. Have only been able to clear the code and get the unit to resume heating once by resetting the breaker, only to have it shut off with the same error code after less than a minute of operation. Am waiting on contact from the seller but am not optimistic since the unit is out of warranty by 3 months and other reviewers seem to have had customer service issues.
Review: Excellent product - Excellent product.

### ⭐⭐⭐⭐⭐ Excellent product
*by U***O on December 10, 2025*

Excellent product.

### ⭐⭐⭐⭐ Does the job
*by L***. on June 11, 2025*

Updating my rating to 4 stars. Customer support was very responsive and sent me a new unit. They sent an EcoTouch 8kW which is more appropriate for my under kitchen sink application. It is smaller, heats/responds faster, and turns itself on after a power loss. Overall I am much happier with the 8kW for my use. Anyone wanting to get hot water to a remote kitchen sink I suggest the 8KW even though the 9KW is same price. ================ Install was easy enough. Usually works but often the temp will not rise to the set temperature. I set mine to 120F, and often it will only get to 108 as shown on the display. Turn it off and on again sometimes fixes it, but several times I have turn off the breaker to reset. This is a hassle to crawl under my kitchen cabinet or go out to garage to reset. If you lose power it does not turn back on, must reach under the cabinet to turn it back on. Would not purchase this brand again, willing to pay more for higher quality.
