Whether one is a student or a teacher or business person who has temporary paper files or whatever.... this is an excellent product

In sum, this is a good product

I strongly suspect these reviews might have received a defective product or perhaps they were using cheap paper that was not hole-punched properly as the opening/closing tab on my binder didn't interfere at all when I would flip pages.

All around great product.

This product appears very sturdy.

Your question: do you require a good product, one likely to last for quite a while

All in all, this is a good product, if it didn't click when I open
