I bought this stove 1 month ago and love the way it quickly heats and love the air fry feature. Coming from a gas stove this unit made the transition less painful. But, not a fan of the cook top showing stains and any little mark from cooking. I like to keep things looking nice and it is impossible to do that with this cook top. While it looked beautiful in the store after using it 1 time the surface had stains on it that would NOT come out! So functionally and mechanically it a 5, but as far as ability to clean and not show cook top stains I give it a 1. For the money I paid I would have expected better.
