The rubber edges don't slide easily - I'll have to get a different music bag for quick in-and-out. It's wider than most binders so music doesn't stick out beyond the cover. Can't they make decent pockets? I need pockets but I put something in both sides and they immediately split at the bottom. Never had this problem with any other binder. Now I have to construct some kind of pockets myself. I like not having to worry about the back collapsing while singing or splitting the way most binders do.
