I have the Go as well but it seems that every quilt I make doesn't use those blocks! I don't have a lot of the dies. I've had it a year and have only used it a couple of times so far. But I like it. I'm not the best cutter and when I've used it my blocks work up more accurately.
One of these days I'm going to cut a bunch of 5 inch squares and things like that with it.
