I expected mediocre quality, but the product was pleasantly surprised.
Not expensive, does its job perfectly. I read the reviews . I guess I was lucky . it works for days . no problems, it pulls it in, it pulls it in. set in the winter . maybe the protection is cooled .
Pros
half an hour. the room is fresh 3x6m.
Cons
noisy . condensate accumulates at the outlet . there is no drain.
