I found a small hollow on top of the oven by the unpacking. This is not serious and does not reach the furnace operation, but damage to the aesthetics. The oven is fine. 2 flaws: too much of the grid positioning hinges hinder the practical side (always look the opposite side to position the grid) and temperature control system and timer are not very accurate (to 20 in 20 ° and 10 min). Note that it is bigger than it looks.
