If you have a lot of papers to put into a binder and you don't want them bent or torn then definitely get these D ring binders the pages will flip with ease.
I USE ALOT OF BINDER BUT THIS IS THE ONLY ONE I HAVE THAT FOLDS THE WAY IT DOES. THIS ALLOWES ME TO VIEW A LANDSCAPE PRINTED PIECE OF PAPER WITHOUT HAVEING TO HOLD IT AND THE BINDER WILL SIT UP BY ITSELF. WORKS FINE FOR WHAT I WANT IT FOR.
These binders are nice but I had to replace it after a couple months because it broke. I feel it should last a school year. So I was a little disappointed in it but I did buy another one so hopefully it lasts longer this time.
