It's automatically graded, can assign practice problems. I like when there is a set A and B in book - I can assign set A and do B in class. It's pretty easy to use.
I wish that I could add an admin user to a section for TAs to easily grade. I also would like a student demo ID to be automatically issued to the professor so that I can see exactly what the student sees. I sometimes have students with issues registering when they have more than 1 connect section. I would like the ability to assign Practice problems without having to assign a due date.
I have benefited 2 ways. 1 - I have saved a LOT of time by not having to grade the homework assignments. Because of the auto-grading, I am able to assign more problems, giving students more of a chance to practice the concepts. Students also ask from practice problems, so I can assign those as well, without giving out any answer keys - they can access the problems and get immediate feedback.
