As others had to say in front of me, when commissioning a pungent odor (preservations ?, coatings?) Develops after burning chemicals. It is therefore essential outdoor (balcony, terrace) make the manufacturer's recommended "burn-in". Thus, it is not done. Even with two or three repetitions of the initial start-up according to the manufacturer of the smell is still uncomfortably strong. That should not be! One might question the parts safe manufacture or obstruct another way, if necessary, carry out the burn-in at the factory. Other manufacturers of microwave ovens, grills, stoves, ovens do not bother their customers indeed to that extent. The smell is now, after 2 months of daily use slowly imperceptible, however, we leave the door to whatever geöfnet a gap even after use. Too bad, because from a performance point can not say anything negative.
