The freezer was purchased in July 2013 and placed in a room with normal temperature. He quickly cooled to -18 ° C but was relatively loud.
It growled and hissed and frequently the compressor went quite often and loudly sounding. The freezer "shuddered" loud, but there was explicit in the illustrated manual that these Geräuschkullise allegedly were normal sounds, I have nothing further thought here.
Until the day when the Kühli was then in a short time to -3 ° C warm and I called customer service (local rate, friendly). The local artisans was there 2h later and could not find a definitive adhoc error, but by measuring the heat and description of daily activities, was typed on compressor failure.
A week later (the Kühli languished at -3 ° C to himself) was called compressor replaced professionally and competently.
And lo and behold:
He Külte in 3h at -18 ° C down, super freezing works, and it is much quieter than my Ikea refrigerator.
It may happen that even with a premium product the technique fails ("Porsche of freezers" !?), the 400 euros frozen stock was rescheduled time. But that in the Operating Instructions no useful description of operation noise and precise cooling capabilities (how fast something is frozen, how high must the temperature variation during freezing his) were present and this fact led to a much later repair as necessary, is irresponsible. Therefore I forgive only 3 stars.
Update 01/03/2014: Because after opening the door of the same Kühli lost 4 ° C and be alert beep went off, this device will now be replaced. My joy is very limited ...
Update in late January: After 2 weeks, the replacement came. He is running as it should be from the very beginning, very quietly, without Temp.schwankungen. Confidence in the storage traffic veeery slowly ....
