In itself this electrical box is a great thing. Instructions and tests are beautifully designed, a lot of accessories here, but now comes the big BUT: what good is anything if after one use it all falls apart and is no longer usable? The fan was made by 2x and switch defect and denied since his service. The connection plug elements go so hard pure that it is almost impossible for a child ineinanderzustecken this, further break very quickly. We are in the first hour already 2 important link blocks shattered downright. Many attempts have now no longer feasible.
