I love the fragrances but am slight disappointed with the diffuser. It is elegant and produces the right amount of fragrance according to your Smart settings. My disappointment lies in the fact that the light feature does not shut off when in the dark. It either stays on throughout the night and day or when in the dark, it lights up then very slowly dims. It then lights up all the way again, and repeats the dimming and lighting non stop. I’ve had to turn the diffuser off completely because it was keeping me up. There was absolutely nothing that was triggering it. I use it during the day and the light stays on. I love the fragrance and waited so long for it to arrive and sending it back is a hassle so I just use it as is. Would have liked to enjoy the fragrance subtly during the night as well.
