I use them almost exclusively for school - I teach and these get beat on regularly. they are the only ones that will hold up to the daily use and abuse at school.
The included inset spine labeling is why I purchased the first one. Stick on labeling can get old and ragged looking. Putting a piece of paper withe the binder contents down the plastic sleeve on a plastic covered binder can be tricky. getting it out to change it can be even tricker. This makes labeling clean durable and easily changable. All the jewel like colors are very nice.
All the features are useful in my work - easy to find the binder among all others binder and reference papers etc. Easy ID due to both color and the Header Page on the front of the binder.
