Olfa makes very good, long-lasting cutting mats.  This is the fourth I've purchased over the last 20 years . . . not because they wear out (the first one I bought is still just fine) but because I need a mat every place I could possibly want to cut . . . sewing room, of course, kitchen, bedroom, and this new one is for our camper trailer.  You can take the girl away from the quilt room, but then the girl just has to take the quilt room with her!  I write quilting patterns and make all my own design samples, so the mat(s) are used often.  No problems in the last 20 years . . . never had to retire an Olfa mat, but have used up a couple other brands.
