As a new quilter I bought the AccuQuilt Go! And a bunch of dies. The dies I liked the best were the strip cutting dies.
However.
I have not touched any of them in years!! It is just as easy to cut your own, unless the specialty shapes are a big part of your quilting. As Linda Schipper said, you have to cut the fabric to fit the cutter, and once I got used to cutting with mat, ruler and rotary cutter, that just made for more work.
