After reading the other reviewers experiences with this app, I threw caution to the wind and purchased it because I couldnt find another application like it. Fortunately, the app works as expected and the videos are just what I was looking for: quick instruction on how to do one specific thing at a time. I use an iPhone 4 with iOS 4.3.1 and I had no difficulty at all downloading, playing, and deleting videos over both Wi-Fi and 3G. If youre a home cook like me, learn visually, and want to learn the fundamentals of precision cuts, fruit preparation, vegetable preparation, meat preparation, poultry preparation, and seafood preparation, I recommend this app.
