I love this binder it stands up and stays put where ever you stand it without additional support no matter how jammed full it may be or even if it is empty. It has a rugged yet very professional look which is what you need for a binder your using constantly daily. Love the ease of changing the spine tab too. These are binders go from one project to the next with ease and still look brand new. The only issue I have experienced is the inside rings need to be stronger and tighter. I use pocket dividers inside these binders for my document storage which can hold a lot of pages but are still very thin at the edge and when flipping through the binder the bottom ring opens ever so slightly and lets the dividers slip out at the bottom ring. So I have to open the rings to slip the divider back in every time. Very annoying but not a deal breaker. Still if it were not for all it's other wonderfulness I would not recommend these solely for that reason alone if you use pocket dividers. And I use both kinds of pocket dividers the plastic and the paper they both unfortunately slip through. Still these are the best on the market today.
These binders never leave me wanting more. Perfect. Front cover opens up with the rings/spine on the back cover so I no longer have to struggle with pages stuck and scrunched from the spine. Do not ever get rid of these binders Staples. They are my go to!
