The shape is fluid and organic, like a big flower bud. As well as black or white, it is available in light wood (I selected) and wood darkens, which is superb, too. It is easy to use, establish and maintain the diffuser (as shown in my video). It is better to clean the tank once a week because it is dirty, it may stop working.
A full tank will last more than three hours, and the humidifier stops automatically and a red light flashes to indicate that it must be completed. Be careful removing covers because there will be plenty of liquid still inside, but below the level of the sensor. Good manual in three languages (including French) with photos, drawings and clear instructions
It can be used with essential oils (such as eucalyptus) that purify the air and help people with allergies or respiratory problems. I love the light that scrolls the seven colors (or you can choose to keep it on your favorite), but in daylight I disable this option useful. It would make a nice gift, or treat yourself. At the price level, it represents very good value for money. In short, I am delighted.
