I highly recommend these binders; they put up with a lot of punishment and keep coming back for more! Like any binders the rings WILL eventually close unevenly but if you take reasonable precautions this will last for a long time. It's a little expensive to use for one-time deals but for anything that needs durable protection this is the way to go.
This is the third time that I had to buy this binder because the rings do not line up evenly and my daughter has had her papers fall out a number of times. If the rings are better constructed so that they close and stay closed I would be inclined to recommend this binder because it lasts in spite of the rings.
This binder is great and I would reccomend it to anyone! However all the contents in my binder are in plastic sheet protectors and even then the pages are hard to turn all the way around the rings in the binder. It takes more effort then necessary.
I've purchased these binders before in varying sizes. This particular binder however is the first one I've encountered from Staples with rings that do not align properly. When I turn pages in the binder they get caught in the ring. Not happy! But I've been too busy to return it to the store and it's probably too late now.
