Query: Great size and great price

I use this mat several times per week. The larger size has decreased the need to change rotary blades so often. With my smaller mat, I would accidentally hit the rotary blade on the table if I ran off of the edge of the mat. This would dull the blades. This new larger mat covers the entire table and it is self healing, so I expect to be using it for some time. The price was about half that of the "name brand" mats of the same size. I haven't noticed any difference between this mat and the much more expensive ones sold in the fabric stores.
