I bought one to organize and show my genealogical data and was so pleased with it that I bought a second binder. It opens easily the pages turn well and the safe archival material is an important factor.
I have several of these binders and they never let me down. The edges are almost indestructible and because of the D rings they don't bind when closing. Well worth the extra cost!
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.
