I started two courses and I was disappointed with the audio quality (for example in the background you can hear children playing and running). I just think this is not professional whatever the value is in the course. You just can not take it seriously and expect that it would be good for you if the person who created the course did not take it seriously. I know that if I was the one charging people for my course I would take it 100% serious because people would expect from me professionalism and to give them some value and knowledge.
