The binder is sturdy and functional. I bought the 1” and it holds the amount of paperwork as expected. I have always liked the D ring better than the C ring as it allows the paper to lay properly and it’s easier to load paper index card dividers etc. Good product.
I like the open and close lever makes it easy access. The plastic compartment in the front is handy to store items related to the contents. A recommendation would be to add a back pocket to slide papers in.
