Product is described a bit irritating: "extra thick" in 120 g / sqm !? The figure shows a roll with a visibly thicker material (at least it lets the suspect), as it is ultimately delivered. It is to describe rather than thin (I had expected a much greater thickness-volume) and most of all it was not rolled but folded at (The amounts I have not yet tested). The shipping took a while, but was ok I'll keep it anyway, because I believe that it offers double wrapped a good winter protection. Would it be a more expensive product, I would have returned it. What leads to the devaluation is the use of the statements and the figure.
