The unit runs quietly (to my mind). I get the frozen food from 2 large free-standing appliances under. The chest consumes only half as much electricity as a standalone unit. So: Half energy consumption (measured it). The device freezes very little. Defrost 1 x / year is sufficient. The defrosting and washing is very fast and much easier than on floor units with drawers. The only drawback, as always with chests: When the unit is full, you will find the underlying things poorly. Since the floor models have the advantage. Who freeze large quantities, here gets a high-quality, cost-effective, economical machine with a lot of space.
