I highly do not recommend this product. It’s a piece of junk.
Does not work the one I received in the mail was used still had water in it. I’m not able to return it. It’s a piece of crap.

Provides a constant supply of hot water at low flow
Installed at kitchen sink. Had to hook up directly to 30amp breaker. Works for doing dishes or to wash my hair at low flow, but that's better than cold water.

Works great I just wish it had been 110volt
I ordered this not realizing it required 220 electric line to run it. I am using it to get hot water to a sink in my outdoor kitchen in our screen room. I ended up having to hire an electrician to run 220 out to the screen room for us so it took a while before we could install it and test it out. It also cost a couple hundred dollars for the electrician so that made this project much more expensive. It was not hard to install but the wiring was not color coded the same as normal wiring, the electrician said he did not believe it was developed for US standards. After using it for a few weeks now I can say that it works well. It definitely produces hot water very quickly and more than enough for our use as a kitchen sink. I love how small me compact it is. We are using it under stainless steel sink like you would see in a restaurant. It is an open shelf under the sink so we mounted the water heater to the wall under the sink and it leaves the whole shelf open for pots and pans and things. Very happy with the outcome but I wish I had noticed it was not 110 when I ordered it.

Hot water for 2 seconds then cold
Only way to make it work is to turn the flow of incoming water down so low that in then becomes useless as water flow is only a trickle. Don't waste your money

Functions well in my cabin
I installed this water heater in my cabin. I needed a way to heat my shower without having to install a big water tank. This hot water heater functions really nicely. Not difficult to install. Really nice quality water heater. And heats water really quickly. Water gets nice and hot. I thought this water heater was a really great value for the money and it functions really well in my cabin.

Does not heat water.
I purchased this item after my first choice failed. This water heater performed in the same miserable fashion as the other one. No heated water of any kind after 90 seconds of running. Definitely not made for RVs.
