Since the cutting mat for these dies is only 6"x6", it looks as if they don't have multiples (except for the triangles). Also 2 of the 8 dies are squares and one is a rectangle -- really easy shapes to cut with a rotary cutter for most of us. I'm thinking they may not be including photographs of the individual dies (something they usually do) because they will highlight the limitations of the sets. They seem more focused on the packaging and easy storage characteristics of the sets (big plusses) and avoiding highlighting the negatives (lack of multiples and some easy shapes).
I think these would be useful for beginning users of the Go! but maybe not so much for those of us who have already acquired some dies and don't do so much with basic piecing shapes.
