I think I've used it about 10 times, and not even for two weeks. I got it, but I'm selling it because the placement interferes with my appliances. Operation has been confirmed. Please purchase only if you understand that this is a used item. I will ship it as is. 【High-Efficiency Humidification Performance】 This humidifier uses ultrasonic technology, achieving a maximum humidification rate of 300mL/h.
