The part is a "niche market". Unfortunately there are too many cheap cell phones, which allegedly also dehumidify the air and not do that for which they are purchased. This part is not cheap, but cheap! It is (s) worth a price, because it dries the air itself off at a certain level, a sufficiently large receptacle has (but who might well be getting bigger!) Itself reactivated when humidity rises again, itself off when the individually adjustable humidity is right and makes a sound to the right next to it allows even a conversation, sleep does not interfere with turning and so on. And maybe is not unimportant that the environment is not ventilated cold by Entfeuchtungstemperatur, therefore represents a sophisticated solution. Operating on sockets with timing is always possible. Since no continuous operation keep the cost of electricity in the context, dehumidification is not just free, but purposefully with this unit and cost.
