First impression when unpacking: Why so extremely thin? OK, I'm not the designer of the product. They will have what is already thought. Fit: My board is 148cm long. Consequently it ought to fit, right? Overhang max. 2cm. Well then we try it. Clamping: With two cheap cords should we contract the thing. The lines are so thin, they can perhaps take as dental floss, or as an instrument of torture in order to cut the hands ..... In moderate force also the part at the board begins to constrict. If your hands until then not bleed, short control and tighten if necessary something. And then it makes "Ratchet" and all that stuff tears it!
