Brand: Francfranc Features: Aroma Diffuser Color: White Capacity: 2 L Operation Mode: Ultrasonic Product Dimensions: 17D x 17W x 31H cm This is an ultrasonic humidifier from Francfranc that looks like an objet d'art. It has 3-level humidification adjustment and a sleep mode, making it functional as well as stylish. You can enjoy aroma water in the water tank and aroma oil in the aroma tray. I used it for about six months. After use, I cleaned it, dried it, and stored it in the closet. There are no malfunctions, so it's still usable. This is a discontinued model.
