Review on 🪡 SINGER 2123 Vertical Needle Zipper Foot: Effortless Zipper Installation Made Easy by Sherri Williams

Zipper foot won't stay in place and moves when sewing. The thread of the screw holding the zipper foot is too small and weak. In fact, without screws, the screw can be inserted into the corresponding hole. This weak screw cannot be tightened and will cause the zipper foot to slip when lowered onto the fabric. This is a manufacturing defect. I used this zipper foot pattern in the 1970's and never had this problem.
