FOR WHAT YOU PAY, IT'S OKAY. It was installed in a sink for dishwashing because the plumbing had a malfunction and it takes a while for hot water to come from the solar panel to the kitchen.

Easy installation. Heats up quickly.

To adequately heat the water, you need to reduce the flow of cold water input from the sink's angle switch. Otherwise, it doesn't have enough time to heat it and the water just becomes lukewarm.

So expect to have a lower flow than usual. It's enough for a sink, hand washing, etc., but for a bathroom/shower, I would look for something more powerful.

I am completely satisfied with its price. Durability and other issues, only time will tell.

With a little more tightening, the fittings broke as they were plastic and really fake.. Better get a faucet with a water heater

    when it works well, it is. the issue is, and I don't know why, many times it doesn't heat up.
    this year only the display works. money wasted.
    12/2025, just before the warranty expired, it broke down completely. it was replaced by the store (honest on their part) but unfortunately, again a problem. sometimes it heats to the temperature you selected, sometimes it acts up and, worst of all, sometimes on its own it hits something like 60 degrees Celsius. I won't go through the repair/replacement process again

    It doesn't work as it should. In the summer, you can barely take a shower, as it doesn't heat up unless you have the water flow set to the minimum. For winter, we won't even discuss it; it can't heat up at all.

    It burned out about 1.5 years later. I hope the warranty covers it.

    It's just fine for washing dishes, after all that's the purpose it serves by design. If you expect it to heat up hot water in the bathroom or to use it continuously, prefer something else more expensive and more powerful. Especially at the price it's at now, it's excellent.
