I buy these binders for my high school-aged son. They don't break mid-year and survive being shoved into his locker and backpack every day. They are worth the price.
I am a online graduate student and to keep organize I use binders. After purchasing several different kinds I came across Staples Better Binder and I have be pleased ever since. The rings have stayed on tract (when closing they line up even after being dropped numerous times.
I use this product for my daily schedule home keeping and home schooling book. It holds all of the information that I require every day. I love how the binder holds up.
