My son went through 3 binders and this one was the last one I bought it is so study even he can't seem to destroy it. It has survived the school locker the football locker and a lot of books piled on it. It's a little pricy but well worth it! I'm guessing it will be a hand-me-down for his brother.
I use this to organize and keep my course documents. It's very durable - unlike other binders I've had in the past. This binder's spine doesn't crack and the rings close tightly but are easy to open and insert pages.
