I have the bias maker. I have no control when it comes to quilting goodies. It works great. I'm waiting for the 2 1/2 tip to be available for it this month. It's fast and folds and heat sets the strip perfectly. It folds straight binding too. Sure saves time. I spent a couple of hours one afternoon turning a jelly roll into miles of 1/2 straight binding.
The strip cutter is not for accurate cutting, I saw that right off when I tried one out and had no use for it for quilting. Now for rag crochet/rug/knitting it would be fantastic. A real time saver.
