The pages don’t move well enough up the slant to make it past where the rings meet

very sturdy and rings stay closed and don't snag the pages

I bought 3 of these binders to hold paperback versions of my college course books and one book fit perfectly with this binder seems like they can hold like 900+ pages well and happy with this binder for heavy amount of pages, it is slightly bulky but it works great

It is sturdy and will fit my needs, but I wish that the pages would turn smoother.
