I really did have high hopes for this binder. As soon as I filled it with the documents it was intended to hold I could tell that it just wasn't going to cut it. The cover was flimsy and the rings were already showing signs that they intended to become unaligned at any minute. It was immediately returned and I purchased an Avery brand equivalent for 20 cents more that is much more suited to hold the documents intended.
I've been buying these binders now for over 3 years and I've found them to be sturdy enough for the jobs I need them for. I use them all the time some every day. The ones I've had for awhile are filled to the brim and they have held up well even with all the weight. Some of them couldn't possibly fit another piece of paper in them! The down side is that the price seems to have gone up significantly since I first started buying them but I guess that's true for many items if not all on this site. Overall I'm please with their performance and will continue to buy them.
