My kids use this as their primary binder at school -- good news it has lasted the entire first semester and hasn't had to be replaced. Considering one of my sons had gone through two heavy-duty binders by this time last year I am thrilled with the quality. Next year we will only buy this type.
My 11 year old son uses this binder daily for school. The binder rings pull apart which make moving papers back and forth very difficult and the papers usually fall out from the binder rings. He had it one day and the bottom binder ring began seperating and the clear overlay pocket in the front ripped.
