What does true European convection mean here?

A fan and a third heating element circulate hot air around the food. That gives more even browning and faster roasting than a standard radiant oven, and both ovens have it.

Does it need a special cutout?

Yes. It is a 27-inch built-in double wall oven, so it fits a cabinet opening sized for a 27-inch unit. Check your cutout dimensions before ordering.

What can I do with the Wi-Fi connection?

It gives access to smart functions from a compatible phone or tablet, such as setting and monitoring the ovens remotely. The cooking itself still works without the app.

Can I use both ovens at once?

Yes. It is a double oven with two separate cavities, so you can bake and roast at different temperatures in the same session.

Is it worth it over a single wall oven?

If you regularly cook multiple dishes or large meals, the second cavity and convection in both ovens earn their place. For occasional baking, a single oven does the job for less.
