I’ve been genuinely impressed with how this electric water heater performs. From the moment I installed it under my sink, I noticed hot water much faster than I expected. It’s compact yet powerful, and it fits perfectly in small spaces like my RV kitchen without eating up room. The temperature gets nice and hot quickly, and I love not having to wait for warm water anymore this little unit delivers exactly what it promises. And for a fair price I’d say. What stands out most is how easy it was to set up. Everything I needed was included, and I had it up and running in no time without any professional help. The build feels solid and well made, and the controls are intuitive. It’s clear that this isn’t a flimsy gadget but something designed to work reliably day after day. Even with frequent use, it hasn’t missed a beat and continues to heat water consistently. Overall, this has been one of the best upgrades I’ve added to my space. It’s saved me water, time, and frustration, and it’s ideal for anyone needing instant hot water in a smaller area like a kitchenette, bathroom, or RV. I’ve recommended it to friends and family already because it simply performs beautifully and delivers comfort exactly where you need it. I’ve heard of some people even using it in there studio apartments by the way so this can have lots of applications of where it’s used.

I installed this under my kitchen sink about a week ago and it's been working great so far. The size is much smaller than I expected which made fitting it under the cabinet easy. The temperature control knob lets me adjust the heat to exactly what I need, and I've found that setting it around the middle works well for washing dishes and quick cleanup tasks. The water heats up quickly once you turn on the faucet, which is convenient when I just need hot water for a few seconds. Installation took some time to figure out the connections, but the instructions helped me guide smoothly through it. I've been using it daily and haven't noticed any issues with temperature consistency. The stainless steel tank seems well-built and the whole unit feels solid. For the price point, this has been a solid addition to my setup.

This review is for the 1.6 gallon unit. I returned the 2.65 unit since it was larger than described in the ad and didn't fit under my sink. I am very pleased with this unit. It fits perfectly under the sink, was fairly easy to install and works like a charm. It heats rapidly. The digital display is bright and easy to read, although it reads in Celsius and not Fahrenheit. It is completely silent, too. For criticisms, it's Chinese made and doesn't even have the manufacturer's name on it. The directions are very inadequate and poorly translated. It says to descale the heating rods yearly, but doesn't give you a clue as to how. It also mentions draining the unit if it won't be used for a long term, but the is no drain plug. There is a round piece on the back of the unit that rotates. There is no mention of what this is or why it's there. Also, there is a pressure relief valve included. The picture of the unit in the ad shows it attached on the top between the inlet and outlet, but there is no connection point on the actual unit. I made the assumption to attach on the inlet side. All that said, the unit is working fine and hopefully lasts a long time.

*UPDATED* STOPPED WORKING AFTER A WEEK COMPLETELY. WONT EVEN ATTEMPT TO WORK! Very cool tool, that works great in seconds. My older 'instant' hit water boiler took a long time to get hot water to my upstairs sink so I decided to take a chance on this and it worked out great! Very easy to install and adjust. Energy efficient and fast! The water temperature is easy to control so you dont get burned. 10/10 homerun!

I'm so happy to finally have instant hot water in my Florida home. I've already installed it in my bathroom. This 1.6-gallon mini tank water heater, a 1500w storage water heater, is small but powerful. It works perfectly, without any problems, and was easy to install.

Installed a bigger one in my other restroom last month. Decided to do this to my master restroom too. Was tired of wasting water and waiting 2 minutes to get water. Now it's scorching in an instance. Easy to install. Fits under my sink vanity with extra space.
