At first (wait for the switcheroo) I wanted to refund this because it was an accidental purchase. I realized I couldn't since it's a new type of product offered on AppSumo, a marketplace item. I was a bit bummed out thinking I just spent $20 on what might be another poor clone of information available in a hundred courses for sale.

However, after I checked out the content available, I have to say that this is an impressive purchase. The information available in these videos is quite robust and there are many videos which contain information that I had trouble finding online. Sure you can get some of these tutorials from other sources, but they aren't as good as these!
