Great controls, simple function and nice calming sound. I am very impressed with thios product. I didn't even know this brand existed until I bought this and I am super impressed with their app, and quality. In fact, I am so curious about their other products I might try their humidifiers next. It has a night mode where it is barely audible and even at the highest fan speed setting it is not an unpleasant sound. Circulates air well in a room and allows us to leave windows open more when the air quality outside is not so great.
