I have been using these binders for years & by far they are THE best binder out there! Durable & Long lasting! Other binders deteriorate over time but these don’t! You won’t be disappointed!
The plastic of the covers isn't thin It's quite thick and dense and I haven't bent it yet. The shape of the rings is good facilitating both holding a larger amount of paper and flipping through it. My only major complaint would be that for maximum durability there should be another thumb tab to open it up at the top not just at the bottom as that improves lifespan significantly. If the lever stops working that breaks a binder in an irreparable way. A petty improvement would be a longer larger window on the spine because the space provided is very scarce. If I try to fit the information on the label it would be too small to read. So far I am very pleased with it It's a fun color which I wanted for my project and those are hard to find. The edges are covered with some softer rubber so that they are less likely to be dented or to dent other things. The only other thing I can say is that it's a little hard to keep a grip on but that's a problem with my meerkat hands and not with the actual binder which I knew was very large before I bought it. Unfortunately I cannot also buy larger hands at Staples.
