Features: -Approx. bottle capacity: 6 -LED display -Bar handle -Digital temperature control -Inside light -Dimensions: 15" H x 10" W x 17.5" D (19.5" D with Handle) This thermoelectric unit is perfect on the kitchen counter or bar. It is different from a compressor unit, and uses a chip and fan to keep the unit cool. You cannot build this in, but why would you? This is such a cute little wine cellar and sure to get attention. It is a normal function of the unit for the temperature to fluctuate. The unit is designed to cycle and this fluctuation of 5 degrees prevents the unit from excessive cycling.
