These are the best binders I've used. The are made durable to last long. I have reused one of these binders for three semesters now, and it stands up to being wedged into my backpack with all my textbooks and laptop. Although it can be initially an expensive purchase, it's definitely worth it in the long run. Because the rings are to the side, and not the center panel, it is easier to fill the binder to capacity. I would recommend to high school and college students.
