It does what it says. I placed it in two closets two weeks ago and despite the heat and the summer heatwave, it has already collected moisture.

Very good, but I believe that in the long run it is not worth it due to the price, especially if we are talking about a room with a lot of humidity! In this case, it is better for someone to invest in a dehumidifier. It fills up very quickly for me, within 10 - 15 days.
