Whisper quite, even when running. It must be very efficient. I originally set the fridge control to "Recommended". But the fridge temperature was close to 1 Celsius, so I turn it almost to "Off" to get the temperature at about 3 Celsius. The freezer temperature at "Recommended" dial is -18 Celsius which is perfect.. The only small inconvenience is no LED light anywhere in the freezer.
I bought this about a month ago. So far it is working as expected. We had an LG with the double doors and freezer in the bottom. We decided to go back to the traditional setup with the single door and freezer at the top. This fridge has much more room and easier to access the contents. Extremily pleased with my purchase so far.
