My advice: Don't get this unless you only want to do occasional pages on the go. I'm a bit disappointed in this punch. It's entirely plastic, and only capable of punching through one sheet of paper at a time. It also relies on your hand strength to do the punching, so punching several pages in a row can be quite jarring on your hands. I'll be saving up for the metal punch. The ruler is a nice touch (but you can buy a filofax ruler much cheaper!)
