Review on VIVOSUN Humidifier Ultrasonic Essential Bedrooms Heating, Cooling & Air Quality by Alexis Hughes

I ordered 2 pieces for 2 small bedrooms. I need one that will allow me to regulate the humidity, but these 2 could not be delivered. After I set the mode to 50%, the devices started working for 10 seconds, then the sensors read that the humidity in the room reached 50% and stop while the room remains at 40% humidity. The problem must be the position of the sensor, it cannot read data because the fog is covering the device. Then I increased the mode to 60% to make the mist spray more often. Come on, even when the device's screen showed that the level was now 55%, it wouldn't start. And when you put it in "sleep mode," which most of us do at night, the mist is automatically at its lowest level and you can't change that. Incidentally, the fog is not sprayed directly, as advertised. They were at a 45 degree angle. If you point the nozzles forward or near the front, fog will cover the sensor and the device will stop. How about directing the nozzles to the side? You get the 10 seconds of work mentioned above, and depending on where you place this device, annoying bright blue lights will shine straight into your eyes at night, as the dark plastic covers are for the front and back only. I like the looks of the devices, but I will definitely be sending them back.
