So far so good. It went to my 12 year old son who is pretty hard on his school supplies. He's only had it for a few weeks but so far it's held up well.
I like the quality of these binders. Some however did not have the raised clip opener. I would prefer that raised opener as it makes it easier to open. I bought several of these binders in different colors and highly recommend them.
I'm a graduate student and these are the best binders I know of anywhere. They're D-ring and the covers are sturdy. I just bought five for this semester because I'll be printing a ton of research articles to write papers on this semester. I know they'll be great to store the articles in later as well.
