I have been using mini ovens for over 25 years. They are convenient for cooking and heating up food. I bake meat, fish, cakes, potatoes, mushrooms quickly and deliciously. Once I bought one with a halogen lamp and I was not satisfied. Since then, I only use ones with resistances. It is easy to clean and can be easily transported to a country house or balcony.

Only for warming up, it's defrosting, maybe a burger. I put a cheese pie to bake, it baked on top and bottom, raw in the middle, the air from below doesn't reach it, it only bakes on the surface on top

I have been using robots for many years from other companies. I bought this particular one and after 3 months it stopped working. I went to the store where I bought it and they kept it for repair. I received it back, but the first time I used it, it stopped working again while it was cooking.
I went back to the store and they replaced it with a completely new one after a heated argument because they told me: "We charged you 5€ for the repair, which we shouldn't have done", even though it was under warranty.
The new one worked for 17 days, about 5-6 times, and then it stopped working. The display shows "oh of", which means it is constantly running and only stops when the timer reaches zero.
Money spent on this particular robot is wasted.
