Preferred the brand you previously carried. It had the opening ‘clamps’ both on top and bottom. This one only has the ‘clamp’ on the bottom and is not nearly as easy to open.
Have bought several Staples Brand D Ring binders and sure enough the rings come apart after a day or two of use. They have to do something to make these rings sturdier. Not sure if the last binder I purchase was defective but the 8 large tabs insertable dividers (item 13516) did not fit correctly. They prevented the ability to flip papers between tabs . . . a real pain
