The EZD Ring may have been heavy-duty, but the book cover itself was not strong to match. Also, the maroon lamination on mine was adhered so poorly that there were three large air bubbles on the inner back flap. I returned this product to the store.
I manage several bowling leagues at Holiday Lanes in Bossier City. The binders I use for league information are always Avery Binders! The Heavy Duty Binders hold up throughout the 30-32 week season, so I don't have eto worry about them falling apart. There is a bonu with Box Tops for Education on each one, too. Great products and work great!
After, I got this, it lasted for 4-5 weeks. It was ready to be trashed after 1 marking period!! The plastic is torn, after many flippings of the binder, and not really fitting in my schoolbag. All my papers, folders, and spirals, after 4-5 weeks, have bent the rings so much that they don't close, and the mechanism itself can't move the rings to open. Ha! One touch. As if, it takes two whole hands to open it! Also, it broke my ruler. I do NOT suggest this.
I really liked these binders. The only problem I have is that the new ones have plastic on the lever used to open them. They used to be metal. I haven't bought one of these since they made the change. It just seems that somewhere you apply repeated pressure should not be plastic.
I frequently drop binders and cheaper ones that I've purchased have broken apart or torn. I love these binders because not only do they have a high capacity, the plastic doesn't stick to paper and the multiple pockets are on the front and back inside covers are the best idea ever! They're also PVC-free AND you get BoxTops.
