I've been using this product for 6 years. I could do basic stuff with it to get along in my work environment. After five years of running and gunning to get the project done, I finally had some time to study this mixer. I decided to buy this course to help me with it. WOW if only I did that 5 years ago I would have saved myself so much time in the last 5 YEARS. Thanks, guys this is a great course, it makes it so easy to understand. Keep it up.
