Personally, I think it is very important to control the temperature of the oven independently. I bought an oven, and the temperature in the middle layer is quite high. I usually put barbecue, roast chicken and baked sweet potato in the middle layer, but I dare not put baked cake and bread in the middle layer, because the color is fast and the bread or cake is not ripe, so I can't see what's inside when I cover it with tin foil. If you put it in the middle and lower floor, the temperature on it is appropriate, but the bottom is too close to the heating pipe. Then the bottom is burnt and the top is not colored. If there is independent temperature control, you can lower the primer by 10-20 degrees, so that the temperature of the fire is almost the same, but the oven with temperature control is slightly more expensive than the oven without temperature control. Oh, I don't have the oven of the brand you mentioned, so I don't know if there is independent temperature control. If you want to buy it or you bought it, you can ask the seller who sold it.
