My basement stank horribly of mold once. With more than 80% humidity actually bummed just about everything in front of it, which may bum ever. Since I have attached some dehumidifier there, the situation has improved considerably. My hygrometer shows meanwhile 60% relative humidity at. This seems to be the maximum that can be achieved with this simple desiccant. At least for me and under my conditions. But this is also sufficient. The mold growth has stopped, the musty smell is gone. Finally even sensitive goods can be stored in the basement.
Conclusion: The product can be recommended. However, I find myself with the package specified on light loggerheads. The specified number of cubic meters you can not really dehumidify with a single package. There should already be a few more packs.
