Takes a while to get the hang of! (23 April 2009)
You have to have a magnetic cutting mat...or a metal work table. The problem I found is that even if you use the magnetic mat and the magnets to hold the paper in place...you still have a problem with the entire mat moving.
It takes a while to get the hang of it, a "lighter" touch is better than force with this item.
It does make a perfect circle, something I don't get when I trace a plate and use scissors.
