It is a rather expensive attachment, but it is helping me. I'll tell you why. When I FM quilted without it, my stitches were too loose underneath due to me not coordinating my speed of foot with speed of hand correctly. When I used it they came out good so I can spend my time focusing on learning FMQing designs right now. I feel like its training wheels and that I'll get better on my own faster from using it. I wanted the tru-stitch regulator so much that I waited till a deal came along that included it for free so Im very fortunate.
