I bought myself the air fryer 6 months after buying my daughter one for Christmas.  I really like the way it cooks the food without leaving the bottom side soggy like a regular toaster oven.  I also like the fact that it cooks most foods that I have tried in about half the time I needed before.  In the beginning you have to be careful with cooking times as many things seem to cook a little faster than the times listed in the book.
