Love these binders!! They are so durable that my kids can even reuse them from yr to yr. When I would buy the other cheaper binders without gray reinforced edges I would have to buy a new binder half way through the school year. They cost a little extra but they are worth it.
I am a student and I have a 3 inch binder. The only compliant I have is that my paper does not turn easy it gets stuck and my rings are not tightly together so they come apart easily. Make sure you examine the rings and make sure they are tight before purchase but yes! I would purchase another one.
Every year I end up buying new binders for my son (age 13). This year was the first year he was able to use last year's binders again because they're in great shape. Last year was the first year we bought this type of binder. Though they're a little more expensive they're worth every penny!
