Essential oil diffuser and humidifier .It is recommended to pour a few drops into the water, I put me a dozen for a more pronounced aroma, I took light wood, it fits well at all decor, diffuses a soothing mist and exchange couleur.J'oubliais it is fairly quiet, just a small aquatic note escapes, but not dérangeante.Trois "timing" of alternative fixed or broadcast but still in color! However it is not worth more than the coupon price (27 euros) a little light object.
