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.
