I use this binder to help keep my units organized for teaching. It is very easy to organize and use. The one push button to open the rings is one of my favorite things and makes using it very easy.
I use these binders daily for my High School Classes. I select a different color for each one of my classes and ask students to get matching color. The transparent slip on front of the binder is home for lesson timeline making it easy to refer to when needed. (Students often ask "what are we doing today") The awesome non-slip surface on binder reassures me of a firm grip when I reach out for it. The bright bold colors are excellent choices for students. And of course the D-ring makes it so much easier to organize the handouts for class. Although I do not demand my students to get these binders I highly recommend that they invest in getting them.
Its a great binder - my kids buy them every year for school. The plastic cover does come off after months of use but the binder itself lasts. They are heavier than others we've tried and its weighty when kids are carrying 3 or 4 of them in backpacks. They are also more expensive but 'you get what you pay for' and these are worth it!
