I bought mine at a quilt show where a guy was demonstrating it - it can be used but there is a hugh learning curve - I agree with quilter 2090 and getting a straight stitch plate will help with the grabbing -- but it takes a long time to get a feel for how to hold the fabric so it curves around with a 1/4 inch seam - I gave up - now make my drunkards path by hand with the curve part and use my machine to sew them all together.
