I have been using the Swingline GBC Binding Machine for about a week and have made several booklets. In my small office, we previously used a manual punching and binding machine using spiral coils, a very time consuming process. I LOVE that this will electronically punch the holes, but do wish it would punch more than 20, as advertised (though I would recommend punching only about 15 at a time as it stuck a little on multiple occasions). I also really love the binding lever that clips the binding in place with great placement and little effort. This machine definitely exceed my expectations.
