This device is very nice, which is wood but not wood but plastic imitation wood, which I was not aware before ordering. The unit is also smaller than guessed at, but that is also pretty and practical, the duration is long relative to the size. I had this device actually ordered because I needed a humidifier, this is the unit in my opinion less geiignet but rather serves solely the duftzersteubung, but works very well. the changing colors of light affect me rather disturbing as pleasant, but this can be switched off fortunately without prblem. Overall, I am satisfied.
