I am not satisfied with the mat. After only 3 months, I sew only from time to time something for my kids and use the supplied rotary cutter, mat does not look nice, cracks where has captures the substance. Self-healing is not for me, a great pity. Of course, I can turn the mat, but since they are no longer just then, well ... About Amazon is having unfortunately given no direct way with the seller to exclude contact, I will seek the same bill. Ruler is great, rotary cutter with a bit of practice as well.
