I like the plastic that it is made out of. It doesn't appear that the edges will crack. It's a rubbery sort of plastic. You can open the mechanism with one finger which is what I like. I would have preferred the label on the spine to go the length and width of the spine like my other 3-ring binders so they would all match as they are displayed on my shelf. This one has a 1"x 4" label. I would have also preferred the inner front and back pockets to go the whole bottom of the binder but instead it goes the whole length of the side.
I use these Binders for my Family Trees - I use the front to insert a family picture which makes it easy to see what tree I'm looking for plus the family name goes into the slot on the side.
I buy all my binders at Staples. I find these particular binders to be durable and do not rip along the seams as other binders to. They are easier to grip because of the rubber edging. The single tab to open the rings is definitely a plus. I would highly recommend these binders.
