These have always been my "go-to" binders and I have them in multiple sizes. I particularly like the 3" binders to keep all my course lectures/handout masters together. I have some of those binders 5+ years and they still work well! The d-ring does hold more and keeps front pages from needing reinforcements/replacement. I do like the rubberized edges (avoids the poking from the sealed plastic edges on cheaper binders). Occasionally I've had to exchange due to faulty d-rings (edges wouldn't engage) but I now just make sure that I check those in the store before purchasing and I'm set.
I love these Staples Better Binders. They are helping change my life and get everything in order. They are nicer than most of the binders that you can buy open and close very easy. They are very sturdy and come in many fun and bright colors.
I like the Staples "Better" View D ring binder. It is quite strong in terms of construction although a bit heavy. It looks good as well. The spine label is easy and quick to use. The binder is a little pricy but in the long run will be worth the expense.
