We've only been using the Bosch KGN39AIAU fridge for three days, but our first impressions are positive. The delivery and installation (via Alza) went smoothly – from choosing a time slot to the punctual arrival, unpacking, and clear instructions for the first switch-on. After being switched on, the fridge cooled down within a few hours and has been running ever since. The design is sober and discreet (in a good way) – the matte stainless steel on the doors looks high-quality. We really appreciate how quiet it is, which was one of the reasons for choosing this model. The drawers in both the freezer and the fridge are well-made. The zero-degree zone in the fridge promises useful storage options, although we haven't had a chance to fully test it yet. The only issue is the layout of the shelves in the door and in the main compartment – the factory setup isn't very practical for smaller bottles or taller containers, so that will need some tweaking. I would also have liked the fridge temperature to be shown directly on the display. Compared to our previous twelve-year-old built-in fridge, this is an improvement in practically every way – the door seal and opening, the amount of space, the separate temperature controls for the fridge and freezer, and the noise level. So far, I can definitely recommend it!
Hassle-free delivery and installation through Alza
A significant improvement in every way compared to our old 12-year-old fridge.
The layout of the door shelves – smaller bottles don't fit.
Not much space for taller containers and large bottles (it can probably be adjusted)
The temperature is not shown on the display.
The sides of the fridge are just grey.

Well-organised interior space; the shelves are flexible
Nicely lit
It is very quiet
The adjustable temperature range starts as low as 3°C
A very practical 0°C drawer that keeps meat fresh for longer
A huge vegetable drawer
The drawers are arranged asymmetrically, which means they are larger than in other fridges and slide out smoothly
The instructions for reversing the door are difficult to understand; they consist solely of pictures with no text. Furthermore, it has been inserted outside the original instructions and contradicts them. I only managed it on the third attempt, after a few phone calls to customer service.

beautiful, both outside and inside
silence
the instruction to change the door opening was not completely understandable, but it worked out in the end
missing CZ/SK/EN manual (there were about 10 other languages), I had to find it online

It is not bad, but it does not reach the quality of my previous fridge (Liebherr).
Looks good.
Quiet operation
The inside is nicely lit
The doors have strong magnets in the seals and are quite difficult to open, they don't have handles to make it easier by using a lever mechanism.
The set temperature signalling looks strange, the light spills over to the ambient temperature, so in the end it is hard to tell what temperature is set (see photo).
The sides of the fridge are not stainless steel, just grey.
