I had a small oven, which cost only half and was quite happy until he broke down one day. So I took this part, at twice the price with convection, tens of thousands of functions and promise. First of all, notice that it is always dark in the oven, so you constantly armed with flashlight is on look at how even the fried food in the furnace. An absolute absurdity in my eyes, to renounce the light. Stands on a pizza that you need 10 minutes it needs at least twice as much time in this oven when not three times, although the correct temperature was set and preheated. The printed temperature on the regulator corresponds well in no case reality. With regard to the circulating air, I personally feel that this is much ado about nothing. The furnace is loud and the pizza changes color even more leisurely than in the upper and lower heating elements. This function can not use in my eyes. The many positive reviews already made me doubt whether my device may be defective, but the same at a friend's work just as bad. Conclusion: If you still have a choice, you should look at the competition, because if you think about it, what makes a oven, here not many overly positive impressions remain, except that it looks good and is compact. Ranging from lack of light up to the super-long cooking times, inconsistent temperatures, etc. which is really just a design flaw made of stainless steel, which can be used at most as home accessory or decoration. I now have almost a year, rarely used it and swap it out, because it just annoys.
