all three of my children use this binder. the construction of this binder is remarkable. no more edges that get caught on bookbags or shirts. we've already gone back to buy more of these for other classes.
I have used these binders in my professional position for several years. Last year I decided to get these for my daughter for high school. I had chosen to purchase cheaper binders before this and had to replace them every year. To my delight these binders held up the entire year in and out of lockers classes floors cars etc. We had to buy one new one this year b/c she "lost" one last year. Yes they are more expensive but worth it when they can be used year to year instead of replacement costs. Staples also has a great deal often where you buy 2 and get one free.
We needed a binder that wouldn't fray or peel. My son is constantly peeling or tearing his folders. This is a perfect solution but wait for sales. They are very very expensive (even with the sale).
