The pad is really good, though it gets after a few years waves, but for 9 euros which is really no flaws, but natural wear and tear! What makes me more concerned about is the fact that Sharkoon says nothing to the material. Just the other day there was a test of how much pollutant is actually contained in keyboards, mice, game pads, etc., mainly in the cables, but the mouse pad smells but also very beautiful, at least the first few days. And with a mouse pad it's just common that you have the hand lying on the pad for several hours.
