the worst.. it dries out and burns on the outside and is undercooked on the inside... especially the potatoes, no matter how much you stir them, especially in the time of the program it has, it's only for very finely chopped and pre-fried ones.. if you put regular potatoes that we cut for frying, it needs double the time from the 35 minutes it says.. it will make some very burnt, some will be completely burned and others will be undercooked because you can't achieve the perfect mixing.. especially those who say it only needs to be stirred once.. normally it needs stirring every 5 minutes.. nothing like our old one which had a stirrer.. such a machine without a stirrer is unlikely to have a good result.. so neither convenience in cooking nor in consumption because I also have an electricity meter, it consumes double what our big kitchen oven does... and the worst part is it also works like a heater.. from the back it loses so much heat that it can warm up the house in winter.. imagine using this thing to cook in summer... it's like turning on a heater inside the house at 40 degrees.. just wasted money.. whoever wants it, I’ll give it away..
