Apart from the Machine scaled perfectly, like any other device also. And needs to be cleaned, like any other device also. Who has the wherewithal buys a 1000 humidifier with 50 Entkalkerpatronen that you may trade each month times. Ok.
Some people make really incredibly stupid, "can not be cleaned", etc. My God, a few hours in water and vinegar insert (also the tank) and thus has sichs. As if we would all come from the Stone Age ...
The appearance of the device is great, that the tank drops, I could not understand - at most, if after one year + times the sealing rubber is porous. And then you swap the rubber just out, is not a special form - something you get everywhere in the trade, and if mans tailoring with scissors.
The volume of the device I find not interfere, provided one makes the unit on a surface that is not prone to handling noise. In an emergency, you cut to (like me) a piece of fitness mat and place it under. Then we hear the "hum" and nothing more - that is the structure-borne sound to the table (or whatever) is taken.
Otherwise, you can hear only a murmur, which I personally, as well as a previous speaker, even as a reassuring feel. After prolonged use over many days the ultrasound plate calcified course and the device is discreet louder. When you clean the device _nie_ I could well imagine that it can be noisy quite. In any case, it is sufficient a little apple cider vinegar reinzukippen and to let the thing stand nen tag that differs the lime on and you can wash it effortlessly => again quietly.
After all counter-criticism but now a real point of criticism: the device is designed in fact for shoebox rooms. As with a previous speaker made it last winter in my 14m² room to increase the humidity measured only from 30% to 35% to a maximum of 38% (after several hours). It is therefore too weak for virtually every normal space. And so I would be arrived at such a cheap device already at the end of criticism.
Anyway, I'm sure that it can cause a lot of joy small children thoroughly. And for 35 ... - the appliance is not hot by the way, less than lukewarm (lower part). The steam ansich always room temperature, in other words you can not to it to burn the little fingers.
My Rating: *** / 5 - recommended with reservations.
