I'm a student taking eight classes this semester. I keep it all straight by color coding everything in these binders. I can tell at a glance which one I'm grabbing from my bag at any given time. I also like that they stay where you put them-- the rubber edges mean that these binders don't move around much when I put them on the table. They're my favorite binders. I only gave them four stars because honestly I could use a few more colors-- another shade of green would be great! I also have a hard time finding white & black binders in the sizes I need in my local store and that's frustrating. Aside from that though they're very useful.
I love these binders. I have several all different sizes. The D rings work great will all 3 hole punched papers. It is very easy to open the rings to add or remove pages. You can fold back the front cover to have a smaller binder to lay on your desk. The clear from allows you to personalize the binder.
