This mini-fridge was purchased for $399 in November of 2014.

This fridge is absolutely silent, and was purchased to replace another fridge which made noise. It doesn't use a compressor, and so doesn't make the humming noise (or any noise) of conventional refrigerators. It is small, but could hold a few days worth of groceries, and snacks quite easily.
