It's The Best!
I think I have tried most the of circle cutters on the market. This is simply the best circle cutter there is. I don't have the 13"x13" glass mat. I have a smaller one, but this works great. HINT: If you have a problem with your paper slipping on the glass mat, keep a roll of blue painters tape handy and tape your paper down. Voila, no slipping and beautiful circles. I needed a huge circle once and ended up drawing around the outside edge of the template and cutting that out. I can't wait to get the oval and the rectangle templates that go with this cutter! The blades last quite awhile, but keep a supply on hand, there's nothing like a fresh, sharp blade!
