Have let the oven (20 ltr. Interior) at the 1st operation 15 minutes (empty) run. For me there was no smoke (which have been highlighted in the description).
Here's my review:
1) the fan noise can be heard virtually no
2) the oven is hot very quickly, the preheating time of Rec. 10 minutes I shorten to 5 minutes. It assumes no lights when the oven has reached the set temperature.
3) baking result of previously frozen buns + Mini Pizza very good, uniform baking result
4) The oven is very hot up, is also logical because it is detached. For the price OK My cats I've seen during the baking time under supervision. Previously they were not interested in the oven.
5) The timer is displayed in the 10-minute rhythm. To 60 minutes setting are possible. When the cooking time has elapsed, you will hear a gong and the oven turns off automatically. I find very pleasant.
6) The oven cools down after switching off very quickly, even above, which I find very pleasant.
7) inside the furnace there is no light. If there is no problem for me, because the mini oven is directly under a light source.
8) The rotisserie I have not tried yet.
9) a large pizza 28 cm in diameter will not fit in. For these cases, I have my normal built-in oven.
10) of the furnace can be heated to 250 °.
11) the furnace is very easy, and for the 20 ltr. quite handy. He is with me on the counter next to the coffee machine and there falls on hard.
He did not 12) circulating air, but I do not miss, because I never use forced air.
I'm very happy and hope to save the product a lot of power, because I mostly sandwiches or casseroles aufbacke made re, which can be very well prepared in this small oven.
