The 520HB I've ordered directly from the manufacturer, he came very quickly. The device makes once an amateur impression, because of its round shape and the light blue container.
But shortly after switching on the hygrometer already begins to react. The specified dehumidification applies (very warm, very humid) for very special conditions. Is it dry, the performance will be lower.
Per day it is in my case about 2 liters, which are taken out, that the tank needs to be emptied once a day at most. In 25l / day you would otherwise several times the rather small container (4l) empty.
The unit operates quietly and it has a decent hysteresis. That is, if it shuts down, then it takes only once for a while until it runs again and everything works again for a while.
The device would constantly switched on briefly and off the refrigeration compressor could not work smart - a waste of energy.
The running noise is okay, it's much quieter than the one half as expensive DIY device. The dried air is blowing upwards. For the basement, I would prefer if the air came out below.
Likewise, I think it would be chic when the device would have a separate on-off switch. Currently on you by turning on the Hygrostateinstellung. So but lost a setting has been found. Here you can but help with a timer or an adapter plug.
Overall, a very useful device. If it lasts a long time, that would be wonderful.
