As our old microwave broke down after many years and a repair would have cost more than a new unit, we bought from a local dealer this MW9718. The facilities etc. seemed perfectly. The shock came, however, when the device is occasionally run after even after short use for a few minutes and has made this noise as if the fans would have struck somewhere. We went at the beginning of a defect, but we have the reviews and then cleared the handbook about the fact that the hunting was normal. Whether the unpleasant noise was normal, we can not judge. For us, however, that was not acceptable and therefore we have returned the device and for a 7675 MW get, which shows no lag time and even a more pleasant operating noise has. Perhaps for this reason, the device is currently not even been taken off the market or available.
