At first I was skeptical - an unknown party to find no tests. And as a price but to the fully equipped device. Then won the curiosity and so far (a few weeks) I'm satisfied. I have the humidifier placed in the office to get the problems my dry eyes at the computer workstation better grip. And in part, under thirty percent humidity of Biel Meier has quite a lot to do. The 4 different working really noticeable Range are very helpful (At level 4 it rains quite around the device), even nicer however the Balance Auto is thus the comparison of the current humidity (measurement accuracy is quite ok) in the room at the set. Also, the timer is determined sense, I have not yet used it. The 5-liter tank is great, but it also leads to a somewhat beefy construction. Whether the built-in filter is good or not only time will tell - at least here has been thought to a security level. Nice are the moisture-proof buttons and the very low noise level. Critical I find changing the water because the tank is inverted upside down on the pedestal and yet still dripping a little water or bottom of the device remains - you should be a little careful. The fact that during the adjustment of the exit angle wet finger gets is worth even mentioning. Only the colorful-shining signal lines could have been omitted from my perspective - my well-being helps the abundant water vapor exuded much more!
