Through exchange for a previously well-functioning - but 15 year old I Bosch ecofroster-have now significantly less freezing capacity - as well as a very low-noise waist-high Miele freezer with comparatively very low power requirements-with a degree precision cooling temperature setting (up to minus 28 degrees). He was hired 18 degree from me to those recommended in the operating instructions -minus. After some gruff delivery / installation (fortunately without defect) I'm with the device very satisfied so far. After about 5 months of operation, a short circuit occurred in the electronics on - questionable by lightning - the display was no longer operable, the device was cooled to -28 degrees and was iced over. Very positive: quick help on AMAZON - contact the Miele Service and repair on service technician after 2 days. After repair and defrosting the device (very easy) now again flawless functioning of the very quiet freezer. The significantly lower power consumption (operating over 24 hours) is understandable in the electricity bill. Very nice.
