Review on FQTANJU CY-20 Side Cutter Cut Sewing Press Foot: A Handy Tool for Precise Fabric Trimming by Wendy Rodriguez

I really wanted this to work. I have the same foot but not in the zipper. Bought to save time but doesn't work nearly as well. It is bound and you must stop the machine and remove the presser foot to remove the fabric. Either the blade is not sharp enough or there is not enough clearance between it and the plate. I've tried it on spandex and it works in very low light, but it doesn't work in anything else. My other leg will go through the seam sewn earlier, not this one.
