However, in a few things just became too much saving or maybe too little thought along:
The panel top and on the sides of very thin sheet is very cheap, the spoils the joy a little, but otherwise has no effect.
The baking sheet is about 1 cm too small, a normal frozen pizza into one photo (eg Ristorante Dr. Oetker). This is annoying because the cooking chamber forth would be more than enough space (on the grid adjusts the Pizza loosely). Thus, there's unfortunately no chance to bake 2 pizzas at the same time.
The insulation falls from very moderate. Especially above the device is so hot that you may burn your fingers. The safety distances described According to the manual (side and rear per 10cm, 30cm above) should comply. A side effect is sure you will consume more energy than good insulation.
The lid does not stop when opened. I mean, he bangs to the handle on the table or when the furnace is close to the edge, with the glass plate on the same. A simple snap would here remedied and prevents damage.
However due to the good baking performance I would have awarded 5 stars and - clearly - at the price you can not expect a premium device. But the disturbing / weak details are so obvious and would be so easy to avoid, that I simply did not understand why that was not thought along here. Thus the device acts carelessly and my fancy to turn a blind eye and deduct only one star.
