The cutting mat has a great rate compared to the same size cutting mats from other manufacturers and the "self-healing" works flawlessly. I gladly would have given 5 stars for this great product to the sensational price. Unfortunately the mat spread even after a week still so much stink that the great room with 30 m² to be aired several times a day. In addition, the unpleasant smell also attracts in the substances as soon as they are placed on the mat, but this can be removed by washing again. If you are not odor-sensitive, I can only recommend the cutting mat!
