Overall these binders are pretty great. I wish I could pull open the rings instead of having to use the push button but this is just a minor thing for me compared to the overall quality of the binder. I love the rubber surround on the binder. It provides a good grip especially when the binders get full & heavy. I stick to the 1 1/2" width binders because I feel almost any binder that gets very large becomes too heavy for me. Once I began using these binders I haven't bought another kind since. Although they might seem a bit pricey so I buy these when on sale or there's a coupon.
I am a teacher. I use these types of binders because they really hold up to lots of use. I see students with these. Other binders are falling apart by May but these binders still look like new.
I like the rubberized hinges for durability. They don't crack like most binders and last longer. I also like the quick spine inserts that come with them as well as the view insert for the cover. They aren't the cheapest but worth the money.
