This is certainly one of the better quality binders I’ve used in my time. Admittedly I haven’t had it for long but I’ve had many a binder where the rings are no longer flushed together when closed and they start to have that little gap after only opening and closing the rings a couple times. I’ve opened and closed this one many times in the last couple weeks and the rings have stayed firmly together. That’s pretty much all it takes for me not to get annoyed with a binder so I’m happy. But there’s also the plus side of the flexibility where the binder bends so I don’t see it beginning to crack as quickly as some other binders do. And it was just as cheap if not cheaper than some of the big brand names out there. Happy with this purchase.
