This water heater works perfectly for its size. It is comfortable, compact, and very easy to install. I used it in my RV, specifically in the sink that I only use for washing dishes, and it performs its function very well. It heats water quickly and makes chores much easier. Definitely a great option for small spaces.

Piece of junk , it had a leak from the start out the box , the inside tank had a small pen hole in it , I would have returned it from the start but needed it for a Christmas Eve party tonight for a extra bathroom sink in my shop . So I repaired the leak and upon putting it back together and installing again the warmest it would get was 80 degrees. Do not waste your money or time as I did

Very convenient to have a remote however since i have cold water running to this unit the flow has to be minimal to heat the water to a decent temperature i may have to get a second one to heat the water with a decent flow

This mini water heater has been a huge upgrade for my sink. It heats up quickly and keeps the water temperature steady, so there’s no waiting around. The fit is perfect for under the counter, and installation was simple. I’ve had zero issues with leaks, and the build feels solid and rust-resistant, so I’m confident it will last a long time. It’s compact but powerful, and it’s been working flawlessly since day one. If you need a reliable point-of-use water heater that’s easy to install and delivers hot water fast, this one’s an excellent choice.
