I'm on my 2nd Olfa 24X36 cutting matt. The other one just got worn out after many years. Bought a Fiskars to try. It was horrible. Everywhere I cut, it cut through a thin layer of the cutting matt. Once there were more than a few chunks missing, it starting to affect my cutting of fabric by skipping, etc. After a week I took it back to JAF and applied the cost of that one to a brand new Olfa.
