I was looking for a fridge that would be as quiet as possible (for an open-plan kitchen and living room), economical, but also large enough and reliable. That's why this one from Bosch caught my eye, as the brand is known for its reliability and it meets all these requirements. The inverter compressor it has also helps with the noise level, providing quiet and smooth power regulation. I've had the fridge since June, so I can give a review based on longer-term use. It usually consumes only about 17–25W (= less than half of my previous fridge). The consumption is only temporarily higher when a larger amount of food is placed in the fridge. At 17W, it's practically inaudible even up close; at 25W, you can hear it slightly. From what I've observed, the indoor temperature has an effect, and probably also how full the fridge is. On cooler days, it usually stays around 17W. It's only noisier during super cool/super freeze, but that's logical because it's working at a higher output. Thanks to its greater height, the fridge has more storage than the previous one, which had the same 60cm width. I also appreciate the design; the handles don't stick out like on my old fridge, saving space – it opens from the side of the door.
The lighting in the fridge is also well-designed, strong enough, and reaches everywhere.
I'll mention the other pros briefly in the pros section.
Probably the only drawback I've encountered in practical use is that when you open the fridge door wide, it doesn't stay in place but swings all the way open. This might be due to its heavier weight, but probably also an uneven floor; it should be okay once levelled.
It's a shame it doesn't have a Wi-Fi connection, for instance, to signal if the door is open, as I might not hear the alarm if I went into another room. Other than that, maybe the heavier weight of the fridge, but that's not really an issue.
Very quiet (inaudible at 17W)

It doesn't have a Wi-Fi connection
The door doesn't stay in place when opened wider, it just opens all the way, but this is probably due to an uneven floor.

So far, I'm completely satisfied. I like its design and functionality. The most important thing for me is the fact that it has two cooling circuits.
The fridge is quiet
2 circuits - that was important for me
Brilliant price/performance.
Nothing comes to mind right now.

I used to have a 70cm wide one. The freezer needed defrosting, but otherwise it was perfect. Now I was buying one for just one person and there was nothing to think about.

Relatively good value for money in terms of features. The shortcomings are mostly just to do with the packaging and appearance. My previous Bosch fridge started rusting near the door after 8 years. That's why I wanted stainless steel, but it's not actually stainless steel, just a decorative finish. It takes an incredibly long time to cool down. According to a separate thermometer with a recording function, it took from 9 in the evening until 6 in the morning for the fridge to cool. So, if there's a longer power cut, and the electricity comes back on and you think 'it's all good now', it will actually take many more hours. The ancient fridge in the cellar cools down in a few tens of minutes.
large volume
quiet
low consumption
frost-free
only a stainless steel look, the material is not actually stainless steel
The side panels have a different colour/finish than the door.
After switching it on, it takes an incredibly long time to cool down, even when it's empty.
Unsuitably packaged for transport, as the swearing delivery driver kept repeating.
