The rings snap shut more quietly than other binders making it less of a distraction in class. I bought a different color for each class making it easier to grab and go.
Best feature is being able to open the rings with one hand - all the action is on the bottom tab and it opens easily. Very well constructed and should last a long time. A bit pricier than I usually spend but worth it.
Finally! A binder that is made to last and which meets my rigorous standards. I like the edges bound in rubber rather than plastic; they don't cut your fingers. I also appreciate the pockets inside and out.
