I have this oven mainly for baking ordered of frozen products. Since delivery is in daily use. While the timer does not work but just as he is to experiment with a little one has herausen quickly how long it takes approximately for each product for home baking. Visually, it could be a bit nicer, but interfere at all, so I do not need it to clear away. A frozen pizza 24 x 24 fit in, in pizzas with 28 x 28 can man the sheet for no longer use, but if it is placed on the grid fits this pure. The oven heats up pretty quickly, so I do not need preheating. The crumb tray I find great, very easy to clean. I am very satisfied so far. Have used it for about three weeks. The points deduction is available for the timer and optics. But still a strong buy recommendation. Am glad that I have not appointed a smaller furnace, since I almost did not need my big oven.
