I use this binder constantly 7 days a week opening and closing up to 20 times a day. Every other binder I have used started spitting at the creases within a couple of months. I would duct tape the cover and within 6 months the rings would separate rendering the binder useless. The rings on this binder lasts at least twice as long and I never have to duct tape! It has never opened when dropped. The best binder I've ever tried.
