Yes, Unlike the "modern" ones that use a predefined cam to set the buttonhole, these are adjustable for length, width, and stitch width of the buttonhole. You can't do "keyhole" buttonholes but everything else is better IMO.
there is a YouTube video somewhere of a person using it that is cool to watch. I particularly like the sound they make in use.
