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 needed something to hold my lab notebooks that could take a decent amount of punishment. This binder fits the bill nicely. The periwinkle color makes it easier to keep track of my lab manuals I keep having students steal them when I use navy blue binders.
Disappointed. The binder was not heavy duty enough. Just days after using the binder one of the rings was already off alignment. My Middle Schooler; a non-rough girl kept it in her back pack. It was not overloaded with paper or misused.
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.
