Love the added quality feature of the reinforced rubberized spine. As a folder that gets slammed around in my teenage son's backpack etc. it seems that this product will hold up to some rough treatment. Also love the option of the easy insert label in the spine though it's not an option that my son uses.
I used these ring binders for project manuals I'm in and out of them everyday while the project continues for 6 to 12 weeks. So far it's performing superbly.
