Works great so far!
Easy to install and works fine still after multiple months of use. I use this for my garage sink and don't keep it set very hot. Just wanted to be able to wash my hands with warm water in the winter, which it does very well. Good value for the money. If I were installing in the house, I would recommend using some kind of pan under it with a water sensing alarm in case it ever developed a leak, which many of these inexpensive units seem to be notorious for

Inexpensive small capacity water heater
Nice little water heater. It gives a minute or so of set temperature water and then its warm water. It does as expected. It’s a small capacity water heater and it’s heating really cold water with a single phase 20amp circuit. Easy to install as well. The adjustable set point is nice and it also displays the actual water temp. We keep it set at 120. Comes with a P&T safety valve as well.

Working beautifully for the first couple of weeks...
I installed it inline with the home hot water system and the water heater seems to be a very good unit... quick recovery, constant temperature, informative display. Yet, as other reviewers have mentioned, there seem to be some installation issues to deal with. Notably, the safety "pop-off valve." NPT threads are supposed to be tapered, increasing in diameter as the pipe is tightened to create a tight connection. But on this unit, the supplied pop-off valve has a rather long threaded shank, even with bit of a smooth material extending past the threads at the end. That wouldn't be a problem, except that the tank inlet for the valve has a pronounced inside lip at the bottom of the threaded inside threads. Thus, the valve bottoms out on the lip before the taper enters far enough to even come close to sealing. I considered remedies, other than wrapping the valve with an "ungodly" amount of Teflon tape, as some have suggested. I considered grinding off the end of the threaded valve to let it go in further, but the extended temperature probe made that impossible. Then going to the local hardware and plumbing store with the heater, hoping to be able to buy a pop-off valve that would fit better... and he DID have one, but rather expensive and relief pressure higher than the one supplied. At his suggestion, I did attempt to solve the problem by both INSERTING A RUBBER WASHER into the fitting... AND wrapping the valve with a copious amount of Teflon tape. Inserted the valve hand tight... and so far, so good. Having gotten over the little hurdle, I would buy again... providing the unit proves dependable.

Heated bidet water
I bought this along with a "Biffy" bidet and engineered and plumed it so that when you wash your "bum", your "back side" with it, it's with nice WARM water!!! Inner body temp is 98 degrees, and this easily sets at 92-94 degrees which makes it perfect, especially for all you women folk!! And, it's power is a standard 120volts so it plugs in to any ole house receptacle!

Defective temperature control
Worked fine for 3 months then the thermostat would not shut down the heating element. Wich constantly released water through the pressure release valve.

Small and convenient and price was really good
Nice and small for my sink. Does not take long to heat back up. I might get a bigger one for my shower. It has a digital display so you can see what the temperature is. I keep it around 120 to 125 F.

water heater
This water heater seems to be working all right of course it’s just in there. I do like the fact that the temperature is on it and tho and I hope that it last longer than the other one that I put in a different kind different brand it lasted maybe a month Two months at the most and quit so I’m hoping this does better and other than that I think it’s very good. Water heater has nothing to do with the one that did quit you know.

HOT water!
So far nothing but positives with this water heater. I have no plumbing background and was overwhelmed with the task of installing this, but once I started I found it to be quite easy and was done in just a few minutes. No leaks so far. Be careful with how much you turn it up though because the first time I turned it all the way up and was so glad I didnt touch the water because it was burning hot. I only have to turn it up a little bit to get a good 90⁰ hand washing temperature. I had an electrician install a 20 amp GCFI outlet where the existing outlet was.
