It seems good, there was only once I had to get the needle plate off to remove the jammed-in fabric - but it was very fine jersey and I was not necessarily using the correct needle, and probably an unsuitable fancy stitch
The buttonholes are brilliant, considering the thin jersey with no interfacing. I love the buttons for presser foot up and down, and the thread cut and tie off - amazing.
One question - does anyone know if I do need the Pfaff bobbins for it? The manual says so, but don't they always...
