Now, after several weeks of use I can say that it is highly recommended. The drying area occupies only half of the room to complete, and the re-tensioning of the cloth is also easier than with single hooks.
What to look for, is the optimal anchoring of the two hooks on the opposite side. At a distance of about 3 m at full capacity utilization namely a considerable weight on it. The accompanying dowels are for a little too weak. My recommendation is to let the anchor to be provided with a finishing putty and harden further. Then it holds bombproof.
