I just got to this unit opted for the dimensions and the energy consumption of A +. The device was delivered very quickly and was well packaged. Twice in the box and still protected with Styrofoam. Now plug in and even hear what he does so for noise. A common living room / bedroom, since I must represent refrigerator already quietly. So a slight noise is heard, comparable to a high-quality notebook fan during normal operation. It is quiet and the fans are running smoothly because the cooler does not work with compressors disappears along with the tiresome turning on and off. The cooler is next to my TV dresser and fits perfectly so. Add to that the blue temperature displays and evening, the white LED's. ;-). Nice to look at ... Operation is virtually self-explanatory and the drinks nice and cool.
