text: Paper folders are very expensive. This one is not and with inexpensive stuff you have trade offs. I have used Yale desktop letter folders before. All have the same issues. If you are looking to just fold a page or two at a time and don't mind a couple of wrinkled folds every 30 or 40 sheets, then this is for you. The problem that I have found with every Yale folder that I have used is that you have to be perfect when you drop the paper in to be folded. Off just a tad and it folds with wrinkles. Sometimes fairly badly. There does not seem to be a way around it. If the unit had guides on the sides to perfectly align the drop in it would be fantastic. As it is, if the letters are personally addressed and you need it to be perfect, you will have a couple or do-overs. For the price, well worth it. Just be patient and careful.
