I now love its effectiveness. Goodies: dual functions of Start button; click the distribution is intermittent, two clicks broadcast is continuous (there is also a second button for the pilot). Under the volcano-shaped lid, there is another cache that isolates the water supply to prevent the diffuser spitting drops of water on the furniture. Steam gushes exactly like the picture. Very good capacity. Even the streaming is done over several hours without the need for adding water. Silent. Stable. It is not far from 5 stars (besides if I could do I would put 4.5), but I read it, it is true that we must find the little trick for open. It does not really screwed, simply turn it counterclockwise to a centimeter to unlock the top, but for sweet or too small hands it is not always obvious. This small detail did not stop me to order a second for the office.
