What to know before buying

The listing claims 0.45 kWh/24h and below 40 dB operation, but does not provide test conditions. Quick-freeze use is said to increase power consumption.
The manufacturer recommends leaving the freezer upright for at least 24 hours before use. For quick freezing, it advises running the mode for 2 hours before adding a small amount of food or more than 10 hours before adding a large amount at once.

Listing details to confirm

Temperature information is contradictory and inconsistent: the title states 14℉ to -40℉, the feature text gives a range of 14℉ to 40℉ without a minus sign, and quick-freeze is described as reaching a minimum of -40℉ to 25℉ after 48 hours. The claimed control accuracy is 1 ℉, while the title also mentions seven thermostat levels. Confirm the intended operating range and controls for the selected listing before purchase.
