I acquired after flooding this utensil, and I can only recommend, I just remove my cellar two days 14litres water.The humidity rate was then 80 or + .Today I am 75% the construction of the unit is excellent, the product looks VERY robust it is slightly noisy, but not annoying (especially in the cellar) short I give this product to its modest size, its finish and its attractive price the maximum score of 5/5
