Visually really great, but the filling of the water is very tedious. You have every time the nebulizer apart rotate in the center, then take out the plastic cap and then you can only fill with water. When assembling it can happen before that you spilled the water in it. In addition, the operating instructions must be read carefully to front turning. Once pressed the power button is interval nebulization. The device turns on every few times and then off again. Who would like to have a functional nebulizer and less emphasis on the appearance, I recommend one of Soehnle or Zen.
