I can say to the product is not much, I refuse to try it. We got it delivered without original package, in a plastic bag. Why? While it was a gatapex instructions here, but the grid paving, not for this. Also I met a more than unpleasant odor from the bag, which I'm not at all accustomed to the company. I use quite a long time the Gatapex tapes as the grid patches, and wanted to try it here. They are also on another carrier film than the grid paving. I am almost of the opinion that there are no originals, I'll get in touch with the VK what that is.
