I bought this refrigerator for my newly built house. The best part is that executives came from Samsung in less than 24 hours for the installation. They gave us a good demo of the refrigerator and how it works. For a middle class man like me, I needed a refrigerator that doesn’t give us a heavy electricity bills. This one has a digital inverter and 4 stars rating that helps in energy saving and also produces very less or no sound. Even though, they said it can be used without a stabilizer I bought one and the refrigerator works with it. I didn’t want to take any risk as our area receives a lot of fluctuations.
