'm A bit disappointed. Due to the overwhelmingly positive reviews I decided to buy it. The delivery took place, as usual Amazon, very fast. When unpacking, I noticed that there were 2 hairline cracks in the turntable. After opening the door, I found that the drive unit for the turntable was installed wrong. So I sent the unit the same day back to Amazon and received in turn very quickly a new device. With this device, I noticed that it noticeably wobbled on a flat countertop, besides the rolls of plastic ring, which is located under the turntable are extremely stiff. The mounting for the evaporator is bolted wrong. I've now stuck Filzpuffer under the unit, made the roles common and the holder again just screwed, because I did not want to return again the device. Apparently one takes it not as accurate in quality control at Samsung. I think for a microwave beyond 100 you probably can expect more. The device works flawlessly so far, therefore 3 stars.
