Use the Ceresit dehumidifier already lange.Wieso? Keep vielllll longer than this strange granules who irgentwo really much CHumidity is towards the granulate after a few days. The tabs on the other hand keep several months and see in the black container still quite nice for a dehumidifier aus.Ein star deduction for the new design, as you probably want to save money by the middle a small hole macht.Sowas is lousy.
