We haven't had it a month and the zipper is already broken.

This lasted 1 month - broke the week after I could return it.

Zipper broke a month after my son started using it

A month after using, the zipper busted

Zipper broke less than 2 months into school year, so we are having to replace it already

This thing didn’t even last 2 months tops.

so my bad, quality o ring binder
