Bought the Foodi Grill about a month ago. Expecting the weather to get cold enough that I would go without grilled food for a couple of months. Used the Foodi Grill for the first time with chicken (skin on) and got excellent texture. Crunchy skin without any of the burning you get from flare ups. Excellent product for indoor grilling. I did find that if you turn the food halfway through cooking the results are much better. 
Now the air crisping is a trial and error endeavor. Trying to air fry French fries was not perfect. I have another air fryer at my other house that does a great job every time. The Foodi Grill has produced great results but you have to adjust halfway through to make sure the time is still correct. 
All in all a great investment and My wife and I have been using it almost every other day. 
Get one!
