This thing really works great. The features are amazing. It preheats your setting and then starts to countdown. You can stop it at any time and make adjustments to the settings. My 2 favorite things about this unit is: you can cook 2 things at once and they finish together and I finally can make perfect bacon without any mess. The oil drips straight down into the drain pan, which if you wrap in foil, can be rolled up and discarded, then a quick wipe out of the inside and you are done. I had an air fryer before that also cooked great bacon, but it was impossible to clean. The heating element was in the same closure as the oven, and I could never get that thing clean. The Ninja has solved this problem. The air fryer is in the bottom oven and the elements are in the top. The fan brings in the heat allowing the 6 surfaces in the bottom oven to be basically flat and very easy to clean. After making bacon I just let it cool (it also tells you when it is no longer hot) give the inside a spray of kitchen cleanser, wipe with a paper towel and done.That's the features, as for how this thing is made and appears, I have to say that I am very impressed. It is very solidly made and it is a very attractive appliance, mostly stainless steel with black trim.I only write reviews when I find a quality product , or a total piece of junk. This is certainly the former.
