have been using this for about a 3 month and it is great. Its pretty straight forward, I mean, its a stove/oven. We don't use the duo feature much but its nice to have. My husband loves to proof bread in the oven. Works like a charm. The air fry is nice but takes much longer than a countertop one. It would be nice if the burners were various sizes. The front one can adjust but the other 3 are the smaller size. These are just little things, overall its wonderful and we love it.
