I've been a user of King material for flight training (both the giving and receiving ends) for many years and would say that 70% of my students end up using one or more of their courses. Over the years, it's gone from grainy videotape with good material to much better delivery means with high quality graphics and embedded video. It's a solid choice for almost anyone in the flight training business.
