We ordered the mat, because we have a very smooth exterior stairs. When it rains, and even more so in this snow is smooth as glass and a threat to every visitor. Not jader expects such a slippery stairs. Anything we have already tested. Floor mats from various DIY stores. From Ikea, we have taken adhesive that are as Schmierkelpapier on top. Everything brought nothing. For a few days I have this mat. In the form of cut and the existing floor mats it. Everything bombproof. No more slipping. I am thrilled limitless.
