I really like this binder except for one drawback. The center clip doesn't always close well enough to flip pages back and forth particularly if using side opening sheet protectors.
I purchased this 3" Staples brand binder for my Macro-economics class in college. I admire the fact that it is a rubberized one so that it is a very sturdy construction and it will stay put and not slide around when I am using it and it won't fall apart like most of the others I've bought and used over the years. I am just sorry that I didn't (and was unable to) purchase another 1 or 2 while I was there. What was I thinking? I knew darn well that I wasn't going to be able to cram all the power point printouts of the slides used in the classroom in there!! I'll certainly be going back real soon and this time I think I'll get 2. Or maybe more...!! :-D
