How efficient is it for its size?
Cohort: every currently registered 300–399 L fridge without a separate freezer sold in Australia, counted once per registration. Star ratings already account for size through the GEMS adjusted-volume formula; this comparison is in raw kWh against models a buyer would actually consider instead.
