My mat from Joanns did not last long. Cheap old white thing..really grooved quickly and badly. so I waited and waited and finally got a super large Omnigrid...that was nice about this one was it came in 3 pieces so I am able to use the size I need. currently have two on my cutting table, have been using for several years and it is as good as new. Omnigrid (Green) makes a great cutting mat, hands down...you get what you pay for.
