a long time ago that I wanted a diffuser and then the product is super Fast delivery, received before the specified time. Indeed the manual is in English but there are no good solutions fifty either. I was really pleased with this product; to see after several uses; I use it for six days and so far nothing to say. Once the tank filled it really last long despite it turns all the time because there are several solutions and I let it run without interruptions and take very long. I highly recommend it; for me not to hesitate
