I have tried 3 different mats and as I have mentioned on here before, prefer the self-healing Olfa. I ended up taking the gray mat (hated that slippery non-healing thing) and the one you are talking about and cut them up to use when I made my own templates. I feel I didn't lose any money by not using them for the initial intended use. Quilting sure is trial and error, and what works for some may not work for others.
