Really Disappointed!
I was disappointed when I opened the box and saw how cheaply made it seems to be.  It does function somewhat, but it doesn't screw together tightly so if you touch it, it falls apart and all your water and essential oils slosh out.  The "Sleep" function doesn't work either which was the main reason I bought this.  Instead of lasting all night, the diffuser turns off within a few hours and the water is used up.  So I'm returning this and will begin my search again to find something that functions better.
