I liked the simplistic approach in which the material was presented. I had the opportunity to attend a course presented by a very experienced pentester with many years of experience. The EC-Council recognizes the best Certified Ethical Hackercourse instructors annually and our instructor was awarded this recognition a few years back. I only became aware about this award after the exam. It would be worthwhile to do a bit of research about your prospective instructor. (I am not sure if information about award-winning instructors is available outside of the ASPEN portal.)
