Fire hazard!! Ordered January 14, had to unplug it July 3rd because it was smoking. Easy to install, plugs in fine...but tripped the breaker every single time. Thought that was the issue so I Had a dedicated breaker installed ..no change. Noticed the smell of burning plastic and saw some smoke so I unplugged it. Not even worth the $50. You get what you pay for.

This little heater surprised me with its power and speed. In just a few seconds I already have hot water, perfect for washing dishes or using in the bathroom without having to wait. I love that it can easily adjust the temperature and that it has LED display, it makes it very practical. The compact design is ideal for small spaces, I installed it under the sink and it takes up almost nothing. In addition, it brings all the necessary protections (against overheating and leaks), which gives a lot of peace of mind. The installation was simple following the instructions, just make sure to place it vertically. Overall, it is an excellent choice for those looking for an efficient and modern solution to get hot water without a tank.

This water heater has exceeded my expectations from the first use. Its instant heating system provides hot water in seconds, eliminating the wait and waste of water. Ideal for quick showers and daily use at home. Its compact design allows it to be easily installed even in small spaces, and its control panel is intuitive, allowing you to adjust the temperature with precision. In addition, it has security systems that provide peace of mind, such as overheating protection and pressure control. The energy saving is noticeable, since it only heats the water that is used, without the need to keep a full tank. That makes it an efficient and environmentally friendly option. As a point to consider, it requires good water pressure to work 100%, so it is important to verify this detail before buying. In summary, a functional, modern and reliable product, perfect for those looking for comfort and efficiency in their hot water system.

I've noticed a significant difference in my energy consumption since installing this unit. The build quality is solid, and the unit is quiet and reliable. I've had no issues with performance or leaks, and the customer support team was helpful with any questions I had. Overall, I'm thoroughly impressed with this Tankless Water Heater.

This Heater worked for less than 24 hours. Now We only get blue lights rotating clock wise in a circle , no hot water. Electric good , water flow good. Heater useless, maybe the blue light will make a good night light. I bought 2 one as back up hook it up after the first broke and 2nd on only has power light no temp ready out and does not seem to turn heater on. These things are trash, total waste of time and money, and have to redo pipeing to fit what I get next. Would of given no stars , I guess one star because it arrived.

There’s no leakage. The temperatures are very accurate. It’s very durable and it looks very professional.
