This oven is very interesting and full of features, it is pretty fast and effectively. For my part, I have to replace it because it had a defect in production and after only 4 months of using the inner pane was broken. Amazon has yet ensured and they resume without me I have to pay anything because the manufacturer whose slogan is "built to last" offer me send me a technician for a mere $ 80 !!! Amazon thank you, I will definitely order again from you because the service is impeccable.
