Personally, I think it is very important to control the oven temperature independently. I bought an oven, and the temperature in the middle layer is quite high. Barbecue, roast chicken and roasted sweet potatoes are generally placed in the middle layer, while baking cakes and bread are not allowed to be placed in the middle layer, because the color changes quickly, and the bread or cake is not ripe, so you can't see the situation inside when you cover it with tin foil. If it is placed in the middle and lower layer, the upper temperature is appropriate, but the bottom is too close to the heating tube. Then the bottom is burnt and the top is not colored. If there is independent temperature control, the primer can be lowered by 10-20 degrees, so that the temperature of the fire is almost the same, but the oven with temperature control is a little 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 an independent temperature control. Want to buy or buy, you can ask the seller who sold it.
