We use the puzzle mat now for over a year. So far it lacks only the inner workings of P and has a toothing disassembly not survived by our son. Therefore, there is a point deduction for durability. Otherwise, the mat provides just on cold floors, a warm, soft game pad. In addition, you can also physically learn the letters and numbers along the way. For me personally, the color is too excited (Fun 2 star deduction), but that's a matter of taste.
