I purchased the binder because it was the right size. In it I put some paper that I use in giving a talk to three classes at the local private school. As I found out it was easy to flip thru the pages with out any trouble.
Good quality for a reasonable price. I purchase all my binders from Staples. I access information from some of the binders on a daily basis and have had many of them for over ten years with no signs of wear. The D ring styling makes it easy to turn pages and also allows for greater capacity in each binder. The mechanism is easy to use; easy to open and easy to close I like the front pocket which allows for easy labeling and the spine pocket is very helpful too allowing you to see at a glance which notebook you are looking for.
I love how easy it is to turn pages in this narrow (1/2" Ring Binder) without tearing out the holes. I like narrow binders because they are easy to keep subject matter focused separating large amounts of information in small binders instead of cumbersome large ring binders that hold information separated index dividers. I use this for complicated devices that are menu driven like my pro-level video camera and my amateur radio equipment.
