I myself, unfortunately, have only a microwave with convection / hot air function and does not provide full oven, so the pizza tray used comes in a wide variety of dishes. For finished pizzas it's almost a little too small (rather choose the 28cm version!), Everything else succeed but almost perfect. The sheet passes for a good heat to the bottom of what is just straight on (better than a rust!). Secondly, the Nuggets do not fall down on the side of an example. In summary: A handy, little helper for microwave lovers.
