Unfortunately, the tests were not to my satisfaction. Although the mat first time visually with the centimeter dimension on one side and the inch dimension on the other side made a good impression, bothered me from the beginning to the extremely smooth surfaces on both sides. In a likewise smooth work surface this mat slips away too often. But also very smooth paper, which I wanted to cut on the mat with Cutter and steel ruler, slipped out and I had a lot of wastage.
In addition, the mat was damaged after a few cuts. The cuts were deep and also lead to wastage. Self-healing looks to me definitely different. Unfortunately I can not give buy rating on this cutting mat.
