For device I can not say much. So far it's only been 3 weeks in use. It cools halt and makes this little noise, just as I had imagined. A temperature display would be desirable, since one has to if necessary. With a separate freezer thermometer equip. An important experience, I would like, however, to share with you. The delivery by the shipping was fast and friendly. The unit has even been unpacked for me to inspect the goods. When I had now found the device at the designated place and before I wanted to connect it, I took the manual again. There, under the item was Unpacking: Warning! Remove the Styrofoam separate part (buffer) between the rear section and capacitor-metal grid (if any). As I asked myself that applies to my device? Under a small semi-free label on the gray Papprückwand I could see that there is Styrofoam. So I started to remove the gray rear wall, so I can get to the Styrofoam. That seemed very strange sometime before because this gray back wall was pretty firmly bonded and do not let easily detach. That can not be right, I thought, when I had the rear half away (and I've even before the cap is unscrewed, to see if it was better to remove from there, but here was all firmly glued) and then I called the hotline from the manual. But still if you could help nobody. I only got a new phone number from Bomann. There are also only a AB answered it, with the information that I have to fill out a form online. After a week I was then informed about denBomann online support, that I should not remove the gray rear wall, this is the isolation and that the device is then no longer reach the power consumption values stated. There was in this case no guarantee when the rear panel is removed. Aha! Meanwhile, I have talked about the imprint directly Bomann and brought in experience that I am not the only one this has happened. This also does not help me and calms me down in any way. A simple sticker on the gray Papprückwand that these can not be removed, would provide clarity. That in this standard operating manual is the question of if it exists, apparently leads to multiple irritations. It's great that I bought a A ++ appliance! The back wall, I then so good we went back glued So let unpacking only of the shipping company and then after a short waiting time (due to the coolant), simply plug in the socket, ready! Steer clear of the manual and of the gray Papprückwand! Thank you very much for your attention!
