Finally I got the range it is so beautiful and powerful. I and my wife fell in love with new range. The old range was broken so I can't use 2 of 4 burners. But now I can use all 5 burners at a single time. It is much powerful than old one. And the oven door can be locked by control panel or app. Therefore my curious baby can't open the oven door. The burners look nice and clean. It can be cleaned very easily. The oven is also very powerful and useful. It cooks very well. Especially the Air-fryer function reduces my cooking time well. I love the Air-fryer oven. I hope one thing it should have the function is the Illuminated Knobs. If it has this function, it can be noticed it is on or off position easily.
