I use 4.5 months. Included was an adapter from a Chinese plug. 20m2 is enough for a room so that the humidity is under 50%. You need to fill the tank twice a day. There is a self-cleaning function, activated through the application. Once a week, the humidifier reminds you to clean it. Pros: Works in scenarios with mi humidity sensors. During the heating season, now the plants do not suffer, it breathes easily, the varnish on the furniture does not crack (it used to crack). Its cons: In the application, you need to set the region of Kyrgyzstan, not even China. It also works as a bluetooth gateway, but sensors from other regions are not connected to it. The built-in sensor overestimates the humidity. After 3 months, it began to leak from below (it turned out that there are even holes at the bottom for draining water, but the Chinese did not guess to make a pan).
