I have two types of zipper feet, the adjustable one, and one with two grooves under the base. The groove is suppose to guide the plastic ridge of the sipper. One is not easier than the other. I have two of the adjustable type, a narrow Singer foot and a generic a bit wider nearly identical to the one in the video. You have to sort lift up the zipper ridge, and guide the foot it along carefully and stitch along slowly go get it nice, almost pushing the foot under the plastic ridge. I guess it's more about technique than any thing else, and I think even zippers different, the plastic interlocking sides can be made different, some are metal, some sort of lift up to the side more easily than others. Some have the zipper ridge lying more flat on the fabric strip.
