I really love this diffuser. It is smaller then I expected but it puts out a great mist. The LED lights are so pretty.. light blue ,pink, red, yellow ,green,purple. It is hard to see in the video so I added some pictures, It runs quietly and the lights make a great night light to fall asleep to. It runs for 4 hours and automatically turns off. Which is great for me since I forget to turn things off or if you are using it in your kids room you do not have to worry that it will be on all night or run dry. It also turns off automatically if it is out of water. It is very simple to use. Takes about a minute to set up. Comes with a measuring cup for water. Fill to the line and pour in to the tank..add any oil you like..plug in and press the button. There is only one button for all the functions. Has three different settings..only mist..mist with changing color lights or mist with your favorite color light. I received this product at a discount. All my reviews are based on my own experience and evaluation of the product so that others can benefit in finding quality products that meet their needs & expectations.
