NO!!! I have one of them and yes they do dull your blades very fast. They are for laying out your fabric for clothing etc. They are not self healing like the Green, pink, yellow etc Self healing boards.
You can use it for routary cutting but as you have found your blade will dull and the board ends up with a lot of cuts in it. I still use mine but I put my self healing cutting board on top when using a routary cutter
