We bought this refrigerator last December 2019 and we’ve been very happy with it. It holds perfectly the temperature inside and the 4th door above the bottom freezer compartment it’s outstanding. Very convenient and easy access for my kids.  We only had a problem when we first got it, the water dispensing unit was dripping water on tray, we called Samsung and they came right away and replace a valve and lower the water pressure on my ice water box valve. It was no problem after that. We were very happy with their service. we highly recommend this refrigerator
