It looks really stylish with the nice display. With the recent dry weather, I feel my throat hurts a bit from the dry indoor air. I am so glad I bought this humidifier, and it definitely helped my dry throat.
I leave it on all the time, and turn it to the sleep mode at time, so the display is off. One refill definitely last more than a day, I just got into the habit of refilling it before I go to sleep every night. It is quiet as well I cannot hear it at all when I am in bed.
