I'm a sophomore in high school and since grade school this is the only binder that I will ever buy. They are quite expensive for a binder but they will last forever. The D-ring is great for not tearing up the binding. The rubber edges are a lifesaver for when you're in a hurry and just need to throw things in your locker. They come in just about every color you can think of which is great because I colorcode everything. Definetly worth the price!
