Go rotary cutting mat
 

Has anybody ever used the Go rotary cutting matt and what did you think of it?

I have used one on the cutting table at retreats. I don't remember any problems using it. I have never used one for the long term.

I have the Martelli and a smaller one and they are very nice when cutting small pieces with accuracy.

The Go! Cutting mat is pretty similar to the Olaf that I use. I haven't worn one out yet but I haven't had it long either.

I have the Go! mat and I like it. It feels the same as the ones I've used in classes (although I can't remember what they were...but not Go!).
