I have the AccuQuilt GO! and I love it. I'm not sure I would ever use it for cutting out a particular quilt pattern, but I love it for cutting up the fabrics leftover when I cut out a quilt with my rotary cutter. It's nice to have the scraps in some kind of storable and usable block. Now, I have lots of different blocks that will go together to make a nice scrappy quilt. It's wonderful to be able to stack and store them.
