I buy these for both business and personal documents when durability is an issue. In daily use they last me for well over a year. Most other designs break down or fall apart well before then. The key is the flexible rubber hinges that resist breaking down with the constant use and abuse they get from me. If you need something that will last and take abuse these are well worth the money. I make special trips to Staples for this very item/
I'm a full time college student and I put this binder to daily use. I am impressed at its durability as I tote it along with my other books and I haven't noticed any blemishes or distortions on the cover. I like the non slip ends as they give stability to the binder while ok on a desk. I recommend the binder to all. I will purchase in the future a need arises.
