Bought this binder for our 12 year-old seventh grader. Within six weeks two of the rings weren't lining up right. This is a chronic problem with all binders I know but I guess we expected better.
I am 8 years old and am using this binder for school. I really like it except that I don't like the D-ring feature. Sometimes that gets annoying to deal with when moving from one folder to another.
This is my fourth year buying these binders. They stay in excellent for the whole 9 months of school. These binders are transported back and forth to school and are used every day. They never break or fall apart.
