### ⭐⭐⭐⭐⭐ Great Little Water Heater
*by D***3 on September 7, 2025*

This heater was easy to install, works as expected. Provides instant hot water. For my needs it was well worth the money.

### ⭐⭐⭐⭐⭐ Satisfied customer!
*by J***N on September 13, 2025*

It’s only been running for less than a week so that part I am not able to address. It is performing very well. Very easy to install.

### ⭐⭐⭐⭐⭐ So easy to install, a cavewoman DID do it
*by D***R on December 7, 2024*

I am in a house I just recently bought. The gas company is super unfriendly, their "inspector," is not a nice person and after clearing the house with the gas on a few months ago now says all the gas lines must be replaced? They're not even old. So, yeah, bye bullying GAS Company! I yanked out the gas stove and put it on Craigslist the next day, lovely electric cooktop now installed. We have options, today. Anyway, I researched and researched, and found this portable electric HWH that consumes low amps and is 110v! I have to admit, the box arrived and I was intimidated. I got online and started looking for "all the stuff," I'd need to install it, lines, fittings, even tools. Imagine my delight when I discovered I needed nothing other than what was already there in the house and some teflon tape I already had. Even installing the pressure relief valve (they provided it, thanks so much) was a breeze. Start to stop, it was making water hot less than 30 minutes after I opened the box. I'm using this right now in a shower. I have to spray, suds, rinse, but it SO beats ice cold showers. My plan will be to use this unit eventually in my outdoor bathhouse, but today, it's saving my life by providing me with a hot shower. So, so happy I bought this.Update 5/12/2025 - Still working great, used it this morning!
