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.
Amazing outer construction as ad promises. Nice attractive look as well. However we returned the 1st binder when the bottom ring would no longer close completely after about 2 weeks of use. The 2nd binder held up longer but all the rings still loosened up quite quickly. Great for use with just papers but not with small notebooks in the rings.
