|A variety of colors are displayed when you choose to rotate the color|
I like the colors that rotate, making it like a night light. It has different length of time options to choose, up to 180 minutes (3 hours). Of course I didn't read the instructions at first and couldn't figure it out, but you hold the MIST button down a couple seconds to get it to turn on. Then, you can click it again and again to adjust the time settings.
Once the diffuser is running, you just click on the color to have the color appear.
This diffuser has 6 color LED lights that you can turn on or off, and the timer goes up to 180 minutes, but you can choose 30 minutes, 60 minutes, 120 minutes or 180 minutes.
The diffuser is ultrasonic -- it has 2.4 million ultrasonic vibrations per second. There is no heating or burning, so the properties of the essential oils are not broken down.
It requires very low energy, and it automatically shuts off when water runs out.
Here is a short video I did to show how to turn it on.
