Never-ending nightmare began with this machine early on. Singer replaced it, still have same problems. 9960 will sew properly then, with no warning, machine freezes, motor makes horrible grinding sounds. Can no longer use it. Singer not interested in helping further so I am stuck with a $500+ sewing machine that does not work. Terrible decision to purchase Singer - it's not the SINGER I grew up with and could depend upon just because of the name.
