I have used your courses at every stage of my career in aviation. PPL-INST-ME-COMM-ATP-CFI While the content is solid, and I find the King's delivery style to be right up my alley, there are a couple of issues. First of all, a few of the questions given on the practice exams were not covered in the presentations. Secondly, and most importantly, the quality of the old original lessons from 20-30 years ago is TERRIBLE! The resolutionis so terrible that it was like everything was out of focus. I got a headache just about every time I watched lessons for more than 45 minutes. When the newer, high definition lessons would come up...it was very easy on the eyes. The old stuff was such a distraction to sit through and probably slowed my learning. Please take the time to reshoot some of the older lessons. By the way, when reading reviews online of your courses, many people make similar comments. "The King's are GREAT instuctors, but the video quality sucks!"
