The Ultrasonic Aroma Essential Oil Diffuser Humidifier Aromatherapy Air Mist Purifier works really good. I like that is has a auto shut off on this diffuser. I also like how it changes color when you have it on and working. There is 2 setting on this, there is a high and a low mist. The buttons are on the front. You can use this just about anywhere there is a USB plug. I have this plugged into my computer and I just love it. I have added a few drops of some of my favorite oils and it makes my room smell great. This diffuser is well made and good quality. I was offered the opportunity to test and review this product for my honest and unbiased opinion.
Update: 2 years and counting. Works great still. I use it daily.
