I 've bought and used these notebooks since 2010 for genealogy records. The ones that are 8 years old are still like new and they get a lot of use. Opening and closing the rings couldn't be easier and they stay aligned. It's the only notebook I'm interested in buying.
I ordered three binders to hold items for a graduation party - certificates awards etc. The binders look sharp but that's about it. Sheet protectors get stuck on the inside rings EVERY time a page is turned and slip out in various places (top middle or bottom ring - not consistent where sheet protector slips out). Same issue with each binder purchased. Would not purchase again.
