I have one of those cutters as well. Love using it. Blades don't last 2 years, have to change them more often than that but much less often then I used to with my Fiskars cutters. I use it on one of those blue mats and it works just great. My cutter, however, squeaks when I use it. It is anoying and probably just needs a little wd40 or something but I don't want to drip grease on my fabs. I use olfa blades with it as when I bought the cutter, there were no special blades or mat, they only made the cutter at that time.
