It's been a month since I said diffuser and I am satisfied for the moment. Just one star less for various reasons: The manual is not easy to read (English / French mistranslated - it is even better to read the English part) inaccurate and incomplete view. For example, it says that if red LED flashes this is that there is more water. I never had the flashing red light because there was always water. However and regularly, it happens that the broadcaster suddenly stops letting the red light. It took me a while to understand the need to change the water became "white" and clean up a bit. Similarly, it is not indicated the use time of the apparatus. For my part, I can leave (depending on oils used) 2-3 hours before having to change the water. A more comprehensive guide is a plus.
