[Upgrade version] The capacity of the water tank has been increased from 150ml to 200ml. [7 LED color changes] With the button, you can adjust the humidifier timer for 3 hours, intermittent work or continuous work. You have the choice between 7 LEDs of magnificent colors. The perfect night light creates a romantic atmosphere and takes you away from the hustle and bustle of modern life. [Less than 35 decibels] With the new ventilation technology, we have integrated a new fan to allow the scented mist to circulate better in a larger area. This fan is designed to operate below 35dB (while all other fans typically exceed 40dB), so it won't interfere with your relaxation. The fan also allows the diffuser to cool down, thus extending its life. [Safety Protection] The 200ml aroma diffuser is equipped with a waterless shut-off function to prevent the overheating in case of lack of water. When the water level is too low, the device will automatically stop. Product size 14.6cm x 10.1cm x 10.1cm Quantity shipping 1 piece
