Review on White 🚿 Bort Crystal Air Sink by Wiktor Stpie ᠌

The instructions describe 3 water levels, which are indicated on the display by a drop of different colors: green, blue and red. I used the sink for a week, the green droplet never burned. When the water level is sufficient, the red droplet lights up all the time and the device turns off. There are very big questions about the built-in hygrometer. At home I have a hygrometer, its readings were very different downwards from those of the built-in hygrometer. I will return the product.
