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!
The outside durability of the binders is great. However the rings that hold the papers in the binder do not hold the product as well as it should. You constantly have to keep aligning the rings to keep your papers in the binder. For the price that was paid for the binder it should have stronger and better construction on the three ring metal holders that are on the inside of the binders.
I do research and I need binders that are sturdy to keep everything organized and together. I've always had the issue that when you put too many papers in the binder and when you open and close it too much the rings start losing themselves....i don't have that problem with this one and I have quite a few of them and none of them have messed up. I recommend this product not only for its durability but because it comes in pink too :)
