I have had one for several years. I have many dies! I am in a quilt group that is doing the 1930 Farmers Wife blocks (6.5 inches). I have the 6 inch Qube (finished size), and there are many of the block pieces I can cut with it. They always go together perfect and are so much easier than rotary cutting or cutting with the templates. I can't cut all of the pieces but I can cut many of them. On some blocks I can cut the whole thing with it. I have the Hunters Star die and it goes together beautifully, as does the Churn Dash, I could go on an on! I have the GO that I use them with.
