I have tried several different binders and have been disatisfied with at least one feature of each binder. When I purchased the Heavy-duty Binder with D-Rings I made an excellenct choice. I love the clear sleeve on the front and back because I can custimize the look of the binder. The inside of the binder offers two clear pockets on the front and in the back. Let's talk about those D-Rings! I love the rings because they open easy have a tight close and do not make a loud noise when I open or shut them. I love the way the front cover of the binder opens and lies flat on the desk.
I love the clear sleeve on the front. It's great for putting my class syllabus list in there for easy access. Both the front and back covers have a 1/4 (like most binders have) and a 3/4 sleeve. The 3/4 works great at holding loose papers in place and they don't fall out when you open the binder. The 1/4 sleeve is good for putting shorter pieces of paper (I like to put my study note index cards there). If you try to put a full size sheet of paper there it tends to fall out when you open the binder. The D-rings make it so much easier to turn pages and they lay nice and flat. The 1-1/2 inch size is perfect for holding all my class notes throughout a semester.
We purchased the 1 1/2" Staples Heavy Duty View Binders with D-Rings for our office. They work very well. We are able to fill these very full of items and never have any problems opening or closing them. And they come in many colors which makes it nice to color-code what we have in the binders sort of an easy filing system. They are definitely a binder that we will purchase again and again for our office. They are easy to use and look very professional. Thanks to Staples for making such great products.
