    Ten years ago, I used an Ultralong water heater, but this time I changed my house and purchased it again. The big brand is trustworthy

    The water heater has voice control, which is very convenient and can automatically turn off the screen. My family said it is very good.

    The first quick water heater I bought was the one I used on the Altrand for over 10 years, and this time I bought a second one. Very useful

    20 seconds of hot water.Overall it’s okay, cheaper than a physical store, and the size and appearance are pretty good.It’s just that I didn’t embed the wire, which makes it look ugly.

    Is it anti scalding? Yes, is it electric leakage? No, delivery is on time. The seller is very good. The color was wrong and they replaced it with a new one that looks good and works well. It heats up very quickly~~~

    A very worthwhile water heater to install, it takes up no space and heats up immediately. The logistics delivery was on time, but the installation was not perfect by the installer. Later, they reinstalled it themselves

    I only reviewed it after using it specifically. It is indeed very good. You don’t have to worry about running out of water when taking a bath. You can use as much as you want. It is convenient and practical.The heat can reach 55, which is enough for a hot bath.

    Not boasting or praising, the quality of the Ultralong water heater is really good. The previous Ultralong basic model has been used for more than ten years, and it was replaced recently because the temperature cannot be adjusted. I look forward to the performance of this model

    This is my first time buying an instant hot product, and I feel flustered. I have been trying it out for the past few days and it feels great. I am not an expert and always consult with customer service and after-sales technical departments. They have patiently taught me in a timely manner, and now I have learned how to use it. The things are really good. Try them out for the winter and buy another house to settle in next spring. We will continue to share the usage effects with everyone in the future. Thank you to the customer service and technical product department staff

    The water heater was installed and the temperature was set at 55 degrees. However, when the water came out, I always felt that the temperature was not hot enough and the water volume was not much. I also installed the Zhongya shower head they sent. It may be because the weather was a little cold during the Chinese New Year. I just don’t feel good enough when I get up.I’m really afraid that sometimes the water heater temperature still won’t come up during the coldest days, which would be really bad.But the after-sales service is very good and they are solving the problem for me. I hope they can solve it well for me.
