Ive had one of these binders for over 15 years of everyday use. scars, scratches, little dings, you name it. - until the day i left it on my van bumper and drove off. - i found it about 2 miles from my house with apparent damage from cars running over it. don't get me wrong i flattened a good portion of it and destroyed the binder completely. but ill tell you this - it saved my IPAD that was inside in its case... enough said.... on to buy another one.
