I have an Olfa, Dritz and Fiskar mat. The Olfa is great. The Dritz is dangerous because your rotary cutter blade tends to slide on the hard slick service. The Fiskar which WAS on my big folding cutting table dulls the blades. I just bought an Arvin I think it's called online for the cutting table. It is huge, self healing, works great, but was expensive and smells bad esp when first arrived. It was $175 for a 40X60, I think. I am away from home for another week, so I can't give more information. I know the name of the company where I ordered was Creative something and it was here in a few days and I think the shipping was free. I got the info for it on another group. If you can get past the dead mouse, chemical smell for a week or two it really works well. When DH came home the day it arrived he came downstairs to my sewing room, sniffed the air and asked me what I'd been doing!!!! We finally left it outside in the sun several days which did help.
