super disappointed 2 2

I'm really disappointed. The oven works very badly. Even at full power (240 °), it took me 1 hour 30 minutes to bake an apple pie with the pastry was not even cooked. I think that the indicated temperature is not good. Ditto for picolinis that in my old turbo chef oven MOULINEX I had for 14 years and has just let go were great gilded in 15 minutes. In this furnace will there must be at least 25 and again, they are barely golden !!! I took the moulinex because I was happy with the old but I did not find the same reference so I picked the convection. Moreover, it's a little newsboy, internal grilles are all still fine compared to the old one which was much better bill. Not recommended so. Extremely disappointed
