I'm a doctoral student with a ton of materials I have to refer to again and again and these binders are perfect for my needs. Durable easy to use - totally worth the money.
I bought one of these when I needed a binder and prefer these binders to the regular less expensive ones. Yes they cost more but hold up much better than the less expensive ones. I use these for long-term storage of documents and need something to hold it all together.
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 looked all over and have tried many types. I am a bit old fashioned and like to keep some records forever. This binder is just right I have used them for a couple of years so far. The rubber hinges feel like they will last a long time and an unexpected bonus is that a stack of binders stays put without sliding onto the floor.
