This is a good binder in that it will hold more pages than the standard 2.5" binder. But the cover and spline of the binder are flexible making it hard to hang on to when filled.
We probably own four dozen of this style binder in all the different sizes. We started using them in 2008 or 2009. Never had one fail. They're vastly superior to all other style three ring binders because of the rubber hinges on the spine and the D-rings. They cost a bit more than other three ring binders but are definitely worth the extra cost.
Heavty duty and big enough to hold all the documents and dividers I need and the ring closes securely without binding the papers and you leave thru them
